Striding at the forefront of spatiotemporal DX
SuperMap GeoAI Technology Successfully Commercializes JHS Ground Assessment Prediction Model Japan Home Shield Corporation (JHS), a leading residential ground investigation company, has successfully commercialized the JHS ground evaluation prediction model using SuperMap iServer GeoAI technology based on ground investigation and analysis data from millions of homes nationwide. This marks an important step toward construction DX(Digital Transformation)and has attracted significant attention. From Spatial Big Data to GeoAI The Ground Support Map, which uses spatial big data from ground survey and analysis, has been highly acclaimed and featured in many media including NHK since it started operation in 2018. We also provide OEM to Kokumin Kyosai co-op and CO-OP Kasai, and are positioning this system as an important system for disaster prevention and mitigation. In Japan, where earthquakes are a major cause of damage to the ground, understanding the ground is the first step to building a safe home. The results of the study were as follows. Although it was difficult to improve prediction accuracy with general-purpose AI, we created a unique prediction model combining a large amount of ground analysis data and geographic information, and by introducing spatial analysis and GeoAI extension modules of SuperMap iServer, we were able to achieve the expected results. This effort is an example of progress from spatial big data to GeoAI, and a major step forward for construction DX. What JHS Geotechnical evaluation Predictions Can Do - First Steps to Construction DX The JHS geotechnical evaluation forecast consists of three pillars. Service for the general public: " Ground Support Map" (https://nlftp.mlit.go.jp/ksj/case_studies.html, an example of the use of National Land Information, Ministry of Land, Infrastructure, Transport and Tourism) is available. Services for businesses: Based on the general public, we are developing Ground Support Maps and land information reports for businesses. We provide a service that enables professionals to obtain geotechnical information prior to construction or land acquisition. Analysis and decision support using AI: In the past, services for businesses were able to acquire necessary information, but subsequent analysis and decision-making had to be done by the users themselves. This time, by using AI, analysis and judgment can be performed more efficiently. Why the JHS Ground Assessment Prediction Model is preferred? - Testimonial from Hideaki Obi, Executive Officer and General Manager, Business Development Division, Japan Home Shield Corporation The quality of the ground is one of the most important factors in eva1uating the property value of land and buildings. Also, in the case of investment and development, whether ground improvement is necessary for construction and, if so, how much it will cost, are important items for planning. Currently, when such geotechnical information is ascertained prior to a geotechnical investigation, it is estimated by a person based on experience, nearby geotechnical investigation data, topography, and other information. The JHS Ground evaluation and Prediction Model solves these problems and makes it possible to predict the condition of the ground more quickly and accurately. We believe that this information service is expected to be utilized in land purchase and investment decisions. We have succeeded in commercializing this service in a short period of time by collaborating with the technology of SuperMap Japan.

In the Era of Spatial Computing, GIS Will Usher in New Development Opportunities (Ⅱ)
To view the first part of the introduction, please click here. GIS products will have wide range of applications in the era of spatial computing Spatial computing and GIS will reinforce each other. GIS is an effective tool for managing and analyzing spatial data. The powerful spatial analysis function of GIS can be used to extract deeper thematic information and comprehensively enhance the utilization value of spatial data. Spatial computing gives GIS more complex spatial analysis capabilities, faster data processing capabilities, and a more intuitive and dynamic spatial data display method. 3D GIS helps build a virtual world and creates a spatio-temporal information base for spatial computing. The commercialization of spatial computing has promoted the vigorous development of the three-dimensional computer ecosystem based on spatial computing and penetrated into the field of 3D GIS. In recent years, the integration of 3D GIS technology and IT technology has greatly improved the integration of 3D data such as tilt, point cloud, and BIM with traditional multi-source data such as images, vectors, terrain data, fine models, underground pipelines, water surface data, and field data. The 3D solid data model has been developed to realize the modeling and expression of the 3D full space and enhance the realism and accuracy of the three-dimensional scenes. True three-dimensional analysis and distributed spatial computing has improved the interaction and visualization capabilities of three-dimensional scenes. The development of large-scale, high-precision urban space intelligent modeling technology facilitates the construction of digital spaces with outdoor and indoor integration, macro-micro integration, and above-ground and underground integration, achieving virtual reconstruction and three-dimensional presentation of the objective world. Spatial computing + GIS has been applied in many fields. Spatial computing is a method to analyze and understand the world based on spatial data and models. From the perspective of technology itself, the combination with GIS technology will have greater potential in urban renewal, community governance, environmental remediation, urban simulation, and service disaster early warning and prevention. 01 Spatial Computing + Digital Twin: Means to Improve Intelligent Urban Management Digital twin city built based on GIS, 3D real-life modeling and rendering technology is a digital world system that corresponds to the real world. In the past, digital twins focused on "visualization", and the application of spatial computing gives the digital twin a soul and makes it calculable and predictable, more intelligent and dynamic. Digital twins based on spatial computing will also have the capabilities of spatial perception, calculation, analysis and retrieva1, and can be applied to cities to build digital spatial intelligent management, truly realizing the transition from "seeing" to "using". Digital twin cities combined with GIS has penetrated into multiple application scenarios: In terms of smart transportation, relying on the technical advantages of real-time twins, traffic big data analysis, AI algorithms and other technical advantages, integrating dynamic and static traffic data and high-precision maps, multiple smart transportation systems can be built by building a full-space computable smart transportation digital twin base. It is an application system that realizes various applications such as traffic accident early warning and processing, public transportation dispatching and management, and traffic information services. In terms of smart water conservancy, by accessing the underlying GIS and BIM data of digital twin water conservancy, business operations and IoT sensing data, and with the help of simulation and spatial computing platforms, intelligent management of various scenarios such as water resources management and allocation can be completed. In terms of smart campus, by accessing IoT sensing devices, geospatial data, BIM data, and teaching business system data, combined with simulation technology and emergency evacuation algorithms, relying on digital twin modeling and spatial computing capabilities, multiple application scenarios can be realized including virtual restoration of campus scenes, safety and security management, comprehensive school situation management and so on. 02 Spatial computing derivative technology: accelerating GIS innovative applications The "spatial computing layer" in the seven-layer architecture of the Metaverse concept has derived concepts such as 3D engines, VR/AR/MR equipment, and geographical information mapping, expanding the business scenarios of GIS in spatial computing. GIS combining AI extended reality technology can superimpose images of the real environment and three-dimensional models of the virtual environment to provide users with a more realistic and three-dimensional geospatial experience. It can realize map visualization, mapping, positioning, intelligent analysis and other capabilities. Combined with GIS High-precision positioning, it can be used in underground pipeline inspections, holographic smart sand tables, urban public facilities management, real-time map navigation, immersive tours in exhibition halls, etc., thereby improving the efficiency of construction, management, maintenance, and inspections, simplifying work processes, and promoting intelligent construction. With the support of spatial computing, GIS combined with AI technology has advantages that cannot be ignored in terms of data-driven, precise mapping and intelligent analysis and prediction. It realizes functions such as forecasting, early warning, previewing, and planning. With the help of VR/AR /MR equipment, it has even broadened the application field of GIS. As a new wave of AI represented by large models is setting off a new industrial revolution, the development of spatial computing platforms will also enable the integration of virtuality and reality to generate more new interactive relationships and new interactive paradigms, which will provide a great opportunity for GIS. The field brings upgrades and changes in technology and tools, and brings various innovative content and applications in remote sensing image analysis, rendering modeling, intelligent interaction, etc., accelerating the realization of SuperMap’s vision—lighting up every corner of the world with geospatial intelligence". The End.

In the Era of Spatial Computing, GIS Will Usher in New Development Opportunities (Ⅰ)
Spatial computing platform may become the next generation computing platform Various extended reality technologies such as VR (Virtual Reality), AR (Augmented Reality), and MR (Mixed Reality) serve as the interface between the real world and the virtual world, providing users with an immersive and hyper-realistic interactive experience. Earlier this year, Apple launched the Vision Pro, the first mixed reality (MR) head-mounted display device. It is a truly revolutionary device that integrates virtuality and reality. As Apple CEO Tim Cook said, Mac brings us into the era of personal computing, iPhone brings us into the era of mobile computing, and Apple Vision Pro will bring us into the era of spatial computing. The underlying logic of the spatial computing era is the spatial computing platform. The generalized spatial computing platform is an information-environment coupling system that takes environmental information and user intentions as input, and takes virtual information presented to the user and operating instructions acting on real space objects as output to realize a direct and complex feedback loop, forming an organic system in which people, environment, and spatial computing devices are coupled to each other. Spatial computing deconstructs and recreates space, making MR equipment a bridge between reality and virtuality, an entrance to a new world of intelligence for all things, and giving birth to a new computing platform. MR devices equipped with spatial computing platforms free up hands and seamlessly integrate digital content into the user's field of vision, providing a more natural and comfortable way of interaction. This also makes spatial computing technology most likely to become the entrance to the future 3D space Internet, completely changing the interaction between people and machines, people and people, and things and things. The relationship between GIS and spatial computing With the development of intelligence in the field of GIS, Geospatial Intelligence was first proposed in 2014, which refers to the ability to extract information and knowledge from spatial data and use it to manage and design the world. In recent years, GIS software has been widely used in the IT field and more and more industries. AI, BI and GI Geospatial intelligence can be embodied as a pyramid structure, with the lowest level being geospatial perception, followed by geo-visualization, geo-decision, geo-design and geo-control. From bottom to top, the level of intelligence is getting higher and higher, and the maturity is getting lower and lower. Geospatial Intelligence Pyramid (GI Pyramid) GIS will become the basic support of the spatial computing platform. The five layers of the geospatial intelligence pyramid cover all aspects of GIS applications and will give the spatial computing platform more geospatial intelligence. 01 Geo-perception–information input for spatial computing In the geo-perception layer, geometric and semantic models of the geographical environment can be established through positioning, mapping and recognition. Geo-perception can realize positioning in complex environments and provide location-related services. Applications based on spatial computing, such as AR navigation and AR multi-person collaboration, are all inseparable from geospatial perception as information input. 02 Geo-visualization-immersive expression of spatial computing The geospatial visualization layer displays geospatial data through the GIS platform, covering GIS technologies such as 2D and 3D integration, 3D reconstruction technology, etc. The geo-visualization layer is the key technology for virtual reality to express the objective world, so as to achieve precise positioning and seamless integration of virtual reality and reality in real-life scenes. 03 Geo-decision–spatio-temporal analysis capabilities of spatial computing Based on GIS spatial analysis, the spatial computing platform is endowed with intelligent decision-making capabilities. Through the integration, analysis and processing of geospatial data, the intelligent application of geospatial data can be realized, such as land use changes, wetland degradation and other issues. 04 Geo-design–scene analysis capabilities of spatial computing Geospatial design is a 3D spatial analysis and calculation on a unified GIS platform. It can provide skyline analysis, slope and aspect analysis and other capabilities in a combination of virtual and real scenarios based on spatial computing, and can assist urban planning and design, municipal management and other applications. 05 Geo-control–the intelligent brain of spatial computing Geospatial control is a higher-level application on top of geospatial awareness, geospatial visualization, geospatial decision-making, and geospatial design. Based on the perceived spatial information and referring to the geospatial data analysis results, corresponding responses can be made, such as agricultural unmanned machinery production, drone control, traffic light control, etc. To be continued...

Combining multiple maps into one to realize "one map" of land There are various types of maps in land applications, including current land use maps, current road network maps, overall plan maps, land consolidation plan maps, construction land control maps, and mining rights maps, exploration rights maps, land reserve maps, land supply maps, land consolidation maps, etc. In addition, there are also auxiliary maps like image maps, DEM elevation maps, standard frame maps, etc. SuperMap Mobile GIS can integrate all these various maps to create "one map" of land. By controlling the visibility, adjusting the order and the transparency, etc., and matching it with different maps, various types of land information can be visually presented. Land "One Map" Split-screen linkage to quickly discover similarities and differences SuperMap Mobile GIS has a split-screen map linkage function. Through linkage browsing of the left and right maps, you can not only compare the land construction planning and land use status in the same time period, understand the construction progress, quickly locate illegal land use, but also compare the land use status at different times, summarizing the construction change trends, and providing scientific reference basis for the new phase of land planning. At the same time, by making full use of the powerful analytical capabilities of two-dimensional maps and the intuitiveness of three-dimensional maps, and conducting two- and three-dimensional integrated split-screen comparisons, the similarities and differences in land supply, reserves, planning, and utilization can be more intuitively presented. With the help of the rolling shutter tool, you can drag the dividing line to easily view the land use development changes in any area. Comparison of land use situation through 2D and 3D integration Accurate collection of field polygons with "three in one" Using the SuperMap mobile GIS terminal as a carrier, field investigators can conduct on-site mapping or verification of land map information. By filling in relevant forms and taking photos for certificates, investigators can quickly grasp first-hand land survey information with the trinity of "map + attribute table + photo". The data collection methods provided by SuperMap Mobile GIS include manual drawing and GNSS collection. During the map drawing process, nodes and line points can be intelligently captured to ensure that the map boundary is clear and accurate. It can also handle adjacent land polygons through segmentation, merging, guiding holes, and other methods to avoid ownership disputes caused by inaccurate shapes. The collected land parcel information is managed in the form of tasks on the SuperMap mobile GIS terminal, including daily inspection tasks, business approval tasks, dispute mediation tasks, special investigation tasks, comprehensive law enforcement tasks, etc., which can be marked as to-be-done, in-process, or completed so that the task situation is clear at a glance; the terminal also provides attribute query, area query, and point of interest query, realizing linkage between graphs and tables, and quickly locating task map polygons.

Full-process 3D pipeline management technology protects a city’s “lifeline”
Pipelines are important infrastructure that ensures the operation of the city. They are called the "lifeline" of the city and carry important functions such as information transmission and water and electricity resources transportation. With the rapid development of cities, the types of urban pipelines are becoming increasingly diverse, widely distributed, dispersed, and highly concealed. As a result, operators and managers face severe challenges to realize refined planning and management of pipelines. To this end, SuperMap has developed a 3D pipeline full-process management technology. After years of technological exploration and accumulation, SuperMap 3D pipeline full-process management technology can realize a series of pipeline data functions from access, expression, processing, analysis, service release to multi-terminal applications, providing effective technical support for the planning and construction, operation management and emergency disposal of 3D pipelines in urban planning, municipal construction, oil and gas storage and transportation, environmental protection and other fields. Technical advantages The 3D pipeline full-process management technology provided by SuperMap has the following advantages: Based on parametric modeling and symbolic modeling capabilities, 3D pipeline scenes can be quickly constructed, which can significantly reduce construction costs and difficulties. It can also improve the display performance of 3D pipe points and pipelines, and greatly improve the data bearing capacity of the scene by effectively reducing memory usage, thereby meeting the management needs of large-scale complex 3D pipe networks. It supports a set of data to be used on desktop, web, mobile, game engines and other multi-end applications. It can quickly improve the visualization of 3D pipeline scenes through the material editor and material mapping. It provides rich 3D spatial analysis and query functions to meet the planning and approval, verification management, operation and maintenance and other full life cycle application needs of pipeline. It provides rich APIs to help developers quickly customize personalized 3D pipeline comprehensive management systems. Functional module SuperMap 3D pipeline full-process management technology includes the following contents: 01 Data access The data access function supports accessing original pipeline data to the SuperMap GIS platform. Currently, SuperMap iDesktopX supports direct access to original pipeline data in .shp/.csv/.mdb/.dwg and other formats, including the pipeline's plane position, burial depth (or elevation), direction, nature, specifications, material, construction time and ownership unit and other information. 02 Data inspection and correction To ensure the correctness of the 3D topology network and pipe well modeling, users need to check whether there are errors in the accessed original pipeline data and whether the attribute fields are complete. If there is a problem with the data, it needs to be corrected and then checked again until the check passes. In addition, when the data does not have an elevation field, it needs to be filled in based on relevant information. For example, the pipe point elevation can be obtained by subtracting the burial depth and pipeline radius from the ground point elevation. 03 Data conversion 3D pipe point data and 3D pipeline data are the basic data for constructing 3D network data sets. The original pipeline data obtained through pipeline detection technology is usually 2D (two-dimensional) data, so the original 2D pipe point and pipeline data need to be converted into 3D point and line data through the data conversion function. 04 Tube well modeling In order to build precise tube well models quickly and in batches, SuperMap iDesktopX provides a tube well modeling function that supports the construction of tube well models based on original 2D pipeline data through parametric modeling technology, thereby accurately expressing various types of complex tube wells. Tube well modeling 05 3D topology network The 3D network data set is the data basis for 3D network analysis and rapid construction of 3D pipeline scenes. SuperMap iDesktopX supports the construction of 3D network data sets with spatial topological relationships based on 3D pipe point data, 3D pipeline data or network data sets. It should be noted that since the resources transported by real 3D pipelines have a certain flow direction, only 3D network data sets with spatial topological relationships can better express 3D pipelines, simulate the real-time flow effect of oil and other resources in pipelines, and carry out various 3D network analysis. 06 Pipe points and pipeline symbols construction There are a large number of different feature points, manholes and ancillary facilities in the 3D pipeline scene. In order to break through the dilemma of manual modeling which is time-consuming, labor-intensive and difficult to maintain, SuperMap iDesktopX supports the construction of 3D adaptive pipe point symbols, 3D point symbols, and 3D line symbols, and can save them in the symbol library for repeated use. The 3D point symbols are used to express wells, valves, water meters and other ancillary facilities; the 3D linear symbols are used to express 3D pipelines; 3D adaptive pipe point symbols are used to express turning points, branch points, intersections, change points, elbows, multiple feature points such as through points. Moreover, relying on the topological relationship between pipe points and pipelines in the 3D network data set, 3D adaptive pipe point symbols can effectively solve the matching problem of pipe points such as elbows and tees with pipelines in the scene. 07 3D pipeline scene construction After the above data processing is completed, SuperMap iDesktopX supports the rapid construction of 3D pipeline scenes using customized thematic maps. In this process, symbolic modeling technology played a crucial role. Symbolic modeling technology automatically constructs a 3D pipe point model and a 3D pipeline model in real-time based on the pipeline direction, pipeline section and other parameters in the 3D network data set, and the constructed 3D pipe point model and 3D pipeline model can be seamlessly connected. In addition, in order to improve the visualization effect of the 3D pipeline scene, SuperMap iDesktopX supports using the material editor to create PBR materials that are suitable for multi-pipeline business and assign them to the pipeline model. 3D pipeline scene construction 08 Service release In order to implement multi-terminal applications of 3D pipeline scenes and 3D network analysis functions, SuperMap iServer supports publishing 3D network data sets as 3D network analysis services, and publishing 3D tiles (S3M) generated based on 3D pipeline scenes as 3D services. 09 Multi-terminal applications In order to realize the sharing and interoperability of 3D pipeline data, SuperMap iDesktopX supports generating 3D pipeline scenes into 3D tiles (S3M). Currently, multiple platforms and software such as desktop, mobile, web, and game engines all support loading, visualization, and applying 3D pipeline scenarios stored using S3M tiles. They also support using 3D network analysis capabilities and 3D pipeline scenarios by loading 3D network analysis services and 3D services. SuperMap iClient3D for WebGL loading oil station S3M data with PBR material More capabilities In order to meet the actual pipeline management needs and help quickly build a 3D pipeline comprehensive management system, SuperMap GIS also has the following functions: It supports the fusion and matching of multi-source data such as pipelines, terrain, urban fine models, and oblique photography 3D models. It supports multiple pipeline data browsing methods such as above ground, underground, rolling shutter, split screen comparison, etc. Pipeline data browsing It provides basic functions such as profile analysis, 3D buffer analysis, and 3D measurement, and can be combined to realize pipeline horizontal/longitudinal profile analysis, clear distance analysis, burial depth analysis, overburden analysis, accident analysis, information query, and statistics. 3D pipeline upstream and downstream tracking (left) and pipe burst analysis (right) Mobile inspection function based on AR+GIS, which can accurately match underground pipelines with the actual scene, thereby quickly viewing pipeline attribute information in real-time, and assisting in completing services such as fault alarms. Mobile inspection It supports the accessing, processing and service release of electromechanical pipeline BIM data to multi-end applications, and can quickly map game engine materials based on S3M data to achieve high-fidelity visualization of pipeline data. Quickly mapping game engine materials based on S3M data and beautifying electromechanical pipeline data In the future, SuperMap GIS will continue to improve the full-process management technology of 3D pipelines, enrich parametric modeling functions such as tube well modeling, and optimize the capabilities of multi-terminal application of 3D pipeline scenarios to further meet the application needs of the smart pipe network industry and be better compatible with the upstream and downstream links.

Xiong'an New Area is a national new area established in 2017 in China. Empowered by advanced technologies in modern times, it aims to be built into an innovative digital city following the high-quality development philosophy. With BIM+GIS+IoT technology, a BIM platform is built to realize intelligent management of the whole area. Six major links cyclically iterated to realize full-process digital control of Xiong’an construction Construction content The construction content of the BIM management platform (Phase I) includes: full-process management of data assets, business function component-level support, implementation of BIM0-BIM5 all-factor cross-industry system review system, safety assurance system and standards, and completion of records of the entire process of new area development, control and management. The subsystems include cockpit subsystem, urban spatial information thematic analysis subsystem, workbench subsystem, current spatial information subsystem, overall planning information subsystem, detailed planning information subsystem, design plan information subsystem, engineering construction information subsystem, and project completion information subsystem. Technical route The construction of the BIM management platform (Phase I) revolves around one "core task", namely: simultaneous planning and construction of digital cities and real cities. The BIM management platform records the digital Xiong’an self-growth by iterating in six major links: the current status of urban construction (BIM0), general planning (BIM1), regulatory plan (BIM2), design (BIM3), construction (BIM4), and completion (BIM5). Overall platform construction plan Technology innovation to create the foundation for the construction of "Digital Xiong'an" The BIM management platform (Phase I) integrates multi-source spatial data to achieve data exchange and business collaboration within the planning and construction bureau and between relevant commissions and bureaus to improve administrative management efficiency and service levels, and provide digital, visualized and scientific decision-making basis for planning and construction issues, laying the foundation for the construction of "Digital Xiongan". As the only GIS platform manufacturer participating in the construction of the BIM management platform for the planning and construction of Xiong’an New Area, SuperMap made use of its own advantages and solved a number of key technical issues to ensure efficient and stable operation of the platform. A digital base that provides massive multi- source data based on WebGL technology The platform is based on WebGL technology and has technical features such as full data, full function support, full time and space experience, and is lightweight and extensible: it supports terrain, images, dynamic layers, field layers and other data; it expands the analytical capabilities of WebGL and fully supports functions such as spatial operations, spatial queries, spatial analysis, and rule modeling. It can handle high-fidelity rendering of complex three-dimensional urban data and facilitate the construction of Web applications. Unified data standards to provide BIM services throughout the whole life cycle The XDB open data format ensures the exchange of multi-professional indicator data such as planning, architecture, municipal administration, geology, etc., and the application and collection of data in different construction stages. XDB remains open in content and format, and can meet the diversity and unification requirements of BIM application software. S3M, as an open and extensible 3D geospatial data format, provides data format specifications for the transmission, exchange and sharing of spatial 3D model data between different terminals, which is of milestone significance in promoting the sharing and in-depth application of 3D geospatial data. Spatial 3D model data format (S3M) Three-dimensional spatial analysis and computing capabilities improve digital approval efficiency The prerequisite for realizing urban computing is to have rich and diverse spatial data models to realize the full spatial expression of the entire urban space. The spatial data model is the geographical information system's knowledge and understanding of real-world urban geospatial entities, phenomena and their mutual relationships. It is the basis for the abstraction and expression of real-world urban objects in computers. Improve efficiency and create a basic technology platform for efficient operation and intelligent innovation Economic benefits 1. Reduce capital investment in duplicate system construction The platform created an efficient and streamlined government approval model for information featuring sharing and business linkage through multi-source, multi-scale, and multi-time and multi-space information fusion and application, which will greatly reduce the duplication of approval and processing work in various departments and reduce the development and investment costs of individual management and approval platforms for various industries in urban management, and then achieve multi-industry and cross-field business collaboration in planning, construction, municipal administration, geology, transportation, land, gardening, etc., thereby achieving the purpose of reducing capital investment and indirectly generating economic benefits. 2. Save administrative costs of repeated collection of information Due to the lack of a sharing and exchange mechanism for existing business information, and in order to meet their own business management needs, various government departments must allocate a large amount of manpower, financial and material resources to collect relevant basic and business information every year. After the platform is completed, on the one hand, it can eliminate a lot of unnecessary duplication of work; on the other hand, it can open up the business information held by various departments, which can greatly reduce administrative costs. 3. Promote effective allocation of resources When the BIM management platform (Phase I) is completed, it will realize effective sharing of information resources, enhance the business capabilities of collaborative work, promote the effective allocation of resources, and greatly improve work efficiency. Social benefits The platform provides a basic technology platform for the efficient operation and intelligent innovation of various management departments in Xiong’an New Area, especially the planning and construction management department. The platform will seize the commanding heights of digital city planning and construction management concepts, standards and rules, and realize the "data-based, informatized and process-based" urban planning and construction management work. 1. Improve the department's ability to perform its functions and the government's credibility The platform makes full use of the national unified e-government network, data exchange platform and modern information technology means, which can give full play to the monitoring and screening capabilities, business operation guidance and information transparency of the information system to realize full-process approval management throughout the status quo monitoring, general planning, control planning, design, construction, and completion, thereby innovating administrative management methods, improving government credibility and execution, and promoting government performance management. 2. Promote the modernization of the governance system and governance capabilities of Xiong'an New Area The platform fully embodies the advanced concept of "people-oriented" and integrates management into services. The starting point and foothold of urban management is to serve the citizens, respect the wishes of the citizens, form a positive interaction pattern between citizens and the government, and jointly manage the city. 3. Establish a "national model" and build a "world model" It is the first to innovate and build a new integrated system of "planning, construction and management" for the development of future digital cities, formulate a new standard system for planning, construction, management, use and maintenance of digital twin cities in Xiong'an New Area. With management innovation as the starting point to increase supervision and service efforts, it aims to become a national model for the symbiosis of digital and real spaces.

The 22nd SuperMap GIS Contest
The 22 SuperMap GIS Contest
Feeling the pulse of winds and storms, GIS escorts China’s 14th National Winter Games
The 14th National Winter Games of the People's Republic of China (hereinafter referred to as the "14th Winter Games") has been held in the Inner Mongolia Autonomous Region from February 17 to 27, 2024. It is the one with the highest standard, the largest scale, and the most comprehensive event in the history of the Winter Games. The organizing committee has very strict meteorological requirements, which places high demands on meteorological support work. During the 14th Winter Games, organizers not only need to observe meteorological data in real-time and every minute, but also need to grasp the weather changes in and around the event venue to ensure the safety of participating athletes, staff and on-site audiences. Therefore, digital means are urgently needed to provide support for the event. In order to ensure the success of the 14th Winter Games, the local meteorological department built a climate disaster risk assessment and climate prediction system, as well as an event transportation and regional traffic weather forecast service system based on the SuperMap GIS platform (hereinafter referred to as the "system"). By providing climate trend forecasts, meteorological disaster risk forecasts, event traffic forecasts and other products and services of various types and time scales, the systems have provided meteorological support for the 14th Winter Games. One Map of meteorological support to provide targeted services Accurate meteorological trend prediction services are an important guarantee for the successful hosting of the event. In order to provide more accurate and comprehensive mid- and long-term prediction service products, the system is connected to BCC-CPSv3 (Beijing Climate Center-climate prediction system version 3-subseasonal to seasonal version 3), CEP-CFSv2, the second-generation American seasonal model product, and DERF 2.0, the monthly Dynamic Extended Range Forecast operational system and other climate model prediction data. According to data time frequency, prediction timeliness, prediction elements and other characteristics, the system compares and tests data from multiple sources, and uses a correction model to correct the data to improve the accuracy of prediction data, and provide more data choices and more accurate basic data information for event weather support work. The system uses One Map to integrate multi-source data on the same date in the same spatial range, and displays the evolution process of meteorological elements through a timeline. By switching data sources, integrated display of live meteorological elements and future trends can be realized, and the time and space information are fully integrated into One Map. The system uses the revised climate prediction data to drive the climate risk prediction model. Combining the model with disaster-bearing bodies such as refined transportation lines, the system provides targeted climate risk prediction services, which improves the visualization of data and enhances the accuracy and practicality of climate risk prediction. One Map of meteorological support during the 14th Winter Games Climate forecast leaves more time for event security decisions Sudden weather will not only affect the event, but may also pose a threat to the health and safety of athletes. Therefore, predicting disaster weather is one of the important functions of the system. To assist with decision-making, the climate disaster risk assessment and climate prediction system establishes extension period, month and other medium and long-term prediction indicators, and predicts extreme weather such as strong winds, low temperatures, and snow disasters. The prediction results are fed back to relevant units 15 days to 30 days in advance so that they can formulate response plans calmly and effectively to reduce losses caused by extreme weather factors. In addition, based on the prediction products, the system can also provide effective reminders to participating athletes, spectators, etc. in advance, and assist in the adjustment of transportation, cold protection, accommodation arrangements and other plans. Estimated risk of strong winds around the venue Traffic forecast provides comprehensive event traffic guarantee In addition to predicting disaster weather, the system can also provide early warning of traffic and road conditions during the event. The event traffic and regional traffic weather forecast service system fully combines GIS technology with traffic weather monitoring and forecasting technology, conducts in-depth analysis of road visibility, road icing, snowfall, etc. around the competition area, and provides forecasts and early warnings and other specialized services for the road network around the competition venue. At the same time, the system also integrates diversified modules such as tourist attraction viewing, ultraviolet intensity analysis, and air quality forecasting to provide comprehensive guarantees for the 14th Winter Games from multiple perspectives. One Map of event transportation guarantee SuperMap Water Conservancy and Meteorology BU (Business Unit) has focused on the construction of meteorological information projects for more than a decade and is committed to providing professional meteorological solutions and services to the industry. SuperMap has participated in the meteorological support work for major national and international events on many occasions, including the 2010 Shanghai World Expo, the celebration of the 100th anniversary of the founding of the Communist Party of China in 2021, and the Olympic Winter Games Beijing 2022. In the future, SuperMap will continue to provide technical support and services for the development of world meteorological industry and meteorological support for major events through continuous cooperation and technological innovation.
AR maps, the "third eye" observing the reality and virtuality (Ⅱ)
To view the first part of the introduction, please click here. Clear at a glance: more expressions Thematic maps use visual elements such as map symbols and colors to express thematic information. It presents complex data and information in an intuitive and vivid way. It is a data visualization tool for displaying specific geographic information and helps users better understand relevant information and improve the efficiency of information transmission. The new version of the AR map can not only make users browse thematic maps at any time in the real scene in the form of a sandbox, but also achieves position and direction matching. By placing thematic maps 1:1 in real scenes, users can grasp geographic information at a glance in real scenes and use and analyze geographic information in actual environments. In precision agriculture applications, the new version of the AR map will include real-time environmental data such as crop growth status data, temperature, humidity, and lighting, and match them one by one to real farmland plots. By regularly refreshing the sensor data of the corresponding plots, it is convenient for users to understand the crop information and environmental data of each plot, so as to detect and deal with abnormal situations in a timely manner and ensure the healthy growth of crops. This not only helps improve agricultural production efficiency, but also helps increase crop yields and provides strong support for farmland management, scientific planting and agricultural planning. Precision agriculture thematic map Diverse formats: more map types AR maps support placing maps, videos, etc. in real scenes, enriching its application scenarios. The AR map format of the new version has been further expanded, adding the ability to directly load xml and kml format maps into real scenes. At the same time, the video format has been expanded, and the video data set produced by SuperMap iDesktop can be loaded directly on the mobile terminal. AR maps are profoundly changing the way we live and work by providing richer and more intuitive geographic information, helping us better understand and adapt to the world. With the development of 5G, Internet of Things and other technologies, AR maps will be integrated with more devices and services, further broadening their application fields. SuperMap will continue to optimize and upgrade AR maps in response to technological development and practical application needs. We look forward to AR maps playing a greater role in the future and bringing more convenience and fun to our lives. End.
AR maps, the "third eye" observing the reality and virtuality (Ⅰ)
As a new type of map that combines virtuality and reality, AR map is changing the way we understand and use geographic information. It can seamlessly integrate elements such as architecture, terrain, vegetation, maps, and multimedia into the real environment, providing users with richer, more realistic, and three-dimensional geographic information. AR maps can not only enhance the user's immersive experience, but also improve the practicality of the map. They provide a new perspective for the application of mobile GIS in construction and planning, environmental monitoring, traffic management, agricultural development, park operations and other fields, and bring more possibilities. SuperMap continues to optimize AR maps in Mobile GIS products. The new version has been upgraded in terms of visualization methods, positioning methods, expression methods, map styles, etc., to enhance immersiveness, practicality, and provide better and more efficient services for AR + GIS applications in various industries. More Visualization Patterns The AR map panoramic visualization mode can map various two- and three-dimensional geographic information and multimedia elements into real scenes, enhancing the sense of reality and improving user experience. In the past, users could only view hidden facilities buried underground, on walls, and in ceilings from the surface, and could not go deep inside to observe the arrangement of facilities and the buried environment. In order to solve this problem, we adopted visualization based on the existing panoramic mode and added two modes: pothole and sliding, so that users can immersively view the hidden facilities buried underground from a richer range of directions and angles. The pothole mode is to dig a hole with adjustable size on the ground, wall and other planes, allowing users to view the buried facilities inside the hole; the sliding mode is similar to the side-by-side map mode. Users can comparatively view the layout of real scenes and hidden facilities from horizontal and vertical directions. Taking the pipeline inspection application as an example, the panoramic mode presents users with the buried distribution of all pipelines; the sliding mode provides a comparative view of the buried pipelines; the pothole mode can help users focus on viewing the distribution and the run of the pipelines in the hole, while also displaying type, color, humidity and other attribute information of the soil. By fixing the line of sight at a specific hole position, users can focus on observing the pipeline or valve at that location, making it easier to focus on the problematic pipelines. Pipeline inspection Positioning methods with higher precision Most mobile GIS applications are inseparable from positioning. Affected by signal quality and environmental factors, the positioning accuracy via traditional GNSS positioning method is unstable and sometimes has errors. This is especially obvious in application scenarios like pipeline inspections and construction stakeout that require high position accuracy. The new version of AR maps adopts two ways to improve positioning accuracy: first, access to high-precision RTK positioning hardware. It supports positioning equipment from multiple brands such as CHC Navigation and UniStrong; the second is the access to high-precision positioning services. It supports positioning services such as CHC Navigation and Tencent. Users can choose the appropriate method based on actual usage needs, thereby effectively enhancing positioning accuracy and updating location information in real-time. In addition, the new version of the AR map also adds a new AR two-point positioning method. Select two corresponding points on the map and the real scene to determine the location of the objects in the real scene. This method is suitable for placing small-volume objects such as bridges, buildings, and pipelines in the real scene. In the bridge acceptance project, the BIM-format bridge model is matched 1:1 to the real bridge position through two-point positioning, so as to compare the virtual and actual construction situation. Bridge information can be intuitively viewed, the bridge height can be measured, and acceptance issues can be reported in a timely manner. Bridge construction acceptance To be continued...
SuperMap cloud GIS software, more efficient, more flexible, more stable and more practical
SuperMap iServer is a GIS software development platform based on high-performance cross-platform GIS kernal. To better meet user needs, SuperMap continues to improve and upgrade the cloud GIS product over the past year including SuperMap iServer and SuperMap iManager: with high-concurrency dynamic mapping performance optimized, SuperMap iServer newly supports cloud-native data formats such as FlatGeobuf and PMTiles to provide more efficient services; SuperMap iManager newly supports distributed map cutting and other functions to run in a Serverless function, and provides automatic detection of service instance status, automatic alarm and exception repair capabilities. Optimized high-concurrency dynamic drawing performance SuperMap iServer has two image rendering methods: dynamic image rendering and cached image rendering. When GIS data is updated frequently, users generally choose to dynamically render maps, that is, instead of generating a cache in advance to satisfy the map request, the server renders the map in real-time every time a map request comes in. However, when concurrent requests are relatively high, it will bring certain challenges to the rendering performance. SuperMap iServer 2023 has optimized the dynamic rendering logic and improved the performance of high-concurrency dynamic rendering from the following four aspects: 1. The GIS data rendering algorithm has been optimized, and the dynamic raster rendering performance has been improved by about 10 times, as shown in Figure 1: Figure 1 Comparison of average response time of PostGIS engine (10million surfaces + 10million lines) for dynamic raster rendering 2. Based on vector pyramid technology, after creating a vector pyramid, although the volume increases slightly, the dynamic Mapbox Vector Tile (MVT) rendering performance is still improved by more than 15 times, as shown in Figure 2: Figure 2 Comparison of average response time of PostGIS engine (10million surfaces + 10million lines) for dynamic MVT rendering 3. Based on image overview technology, after creating an image overview, the dynamic rendering performance of image services at small scales is improved by approximately 100 to 600 times, as shown in Figure 3: Figure 3 Comparison of small-scale image rendering performance before and after creating an overview 4. The image rendering performance under the dynamic projection of image service has been optimized. The performance is improved by more than 1.5 times under 32 concurrencies (as shown in Figure 4). As the number of concurrencies increases, the performance improvement becomes more obvious. Figure 4 Comparison of average response time of dynamic image rendering under dynamic projection of image service Query and rendering performance optimization based on FlatGeobuf technology FlatGeobuf is an open-source data format with a small size. It uses Hilbert R-Tree spatial index, supports fast bounding box spatial filtering (partial loading), and has better client-side rendering performance. Thus, it is recommended as one of the preferred formats by the industry for transmitting spatial data through HTTP/"cloud". Nearly 20 REST interfaces of SuperMap iServer 2023 such as query and analysis newly support FlatGeobuf (FGB) representation, further improving the transmission and rendering efficiency of query and analysis results. FGB representation has three major advantages: 1. The upper limit of the amount of data loaded on the web side is larger Take data query as an example: when the data query results are completely loaded on the Web, the FGB representation can reach 200,000 aspects, which is 10 times the number of GeoJSON, greatly improving the display experience of large-scale data. 2. The representation volume is smaller Figure 5 Comparison of query result volume of FGB representation and GeoJSON representation returned by data and map queries As shown in Figure 5, the query results of FGB returned by data and map queries are about 40% of the GeoJSON representation when fully loaded. The volume of partial loading is smaller than that of full loading, which effectively improves the transmission efficiency of query results. 3. The efficiency of query and rendering is higher Figure 6 Comparison of the completion time from query execution to web rendering of FGB representation and GeoJSON representation As shown in figure 6, the efficiency of FGB representation from query execution to web-side rendering is more than three times higher than that of GeoJSON representation, so the partial loading performance is better. The larger the amount of query results returned, the more obvious the advantage. Serverless functions continue to be updated, making function calculations more flexible yet more stable Serverless, as a new generation cloud computing model, can greatly improve elasticity and reduce operation and maintenance costs. In 2022, SuperMap applied Serverless to the GIS field, to support spatial analysis services, processing automation (GPA) services, geometry services, mobile alarms and enterprise WeChat remote control functions to run in a functional manner. In 2023, we newly launched distributed map cutting services and Web printing services that run in serverless function mode. The services run faster, scale more elastically, and thus saving resources to meet in-depth business requirements. The distributed image cutting service can run in a Serverless function mode, which not only solves the pain point of traditional single-machine image cutting and caching that consume a long time, improves the efficiency, but also has an automatic fault recovery mechanism to ensure stable image cutting on the server side. The capabilities are mainly the following: 1. Under the demand for massive tile production, graph cutting microservices face difficulties such as high computational intensity and long execution time. After being disassembled into functions, automatic elastic scaling and automatic exception recovery are faster, making the GIS system more elastic and resilient. 2. More fine-grained, independent functions are responsible for the cutting, distribution and parallel graph cutting, which improves system stability and high availability. 3. In face of a graph cutting task that consumes huge resources, the function will only be started when there is a task, and the resources will be released immediately after the task execution is completed. In this way, resources will be utilized in a more efficient way. Figure 7 Topology diagram to view functions running on demand Intelligent detection, alarm and repair of service instance status, making service monitoring more reliable Faced with a large number of GIS service instances, some abnormal instances can only be checked manually one by one to verify their availability. Not only is the operation and maintenance cost high and inefficient, but it is also difficult to ensure the accuracy of the verification. SuperMap iManager 2023 newly suports service instance status monitoring capabilities mainly including: 1. Support for automatic detection of GIS service instance status, making abnormal services clear at a glance. 2. Providing filtering capabilities based on service status, which can filter out the three statuses of GIS service instances: normal, abnormal, and undetected as needed, and easily locate specific "problem" services with one click. Figure 8 Filtering service instances based on status 3. When the service instance status is abnormal, SuperMap iManager triggers an automatic alarm. It can promptly remind users to understand abnormal service instances. 4. For service instances with abnormal status, the system has added automatic abnormality repair capabilities, which greatly reduces operation and maintenance costs and makes system monitoring more intelligent. The GIS service instance status monitoring capability improves the practicality and reliability of the product, and provides a "boost" for users to smoothly and efficiently publish services and use GIS systems.

SuperMap iServer Image Service Assist Image Processing Throughout the Whole Application Process
With the rapid development of remote sensing technology, the means of obtaining remote sensing images have become increasingly abundant, the amount of image data has exploded, and image applications have been put into use across all walks of life. As a result, how to efficiently manage massive remote sensing image data has become an industry problem. Users often face issues like duplicate data storage and difficulty in data retrieval in image management applications, drawing attention to a series of problems in data application, release, and data services in the industry. SuperMap iServer, a server platform launched by SuperMap integrates image data processing, data management, service publishing, data application, and intelligent interpretation services in one platform, realizing the integration of the entire image processing and effectively solving many problems in image applications. This article focuses on a key role in the whole process of image application - SuperMap iServer image service. It realizes efficient and unified management and rapid release of multi-source and massive images, enables barrier-free data connection in all aspects of the entire process, and helps the industry build an integrated image application system. Efficient and unified management of massive images Image service provides a new model for the management and release of massive image data. Images are managed through services, and organized according to the classification of different collections. The images are ultimately managed by mosaic datasets. The mosaic data collection is an image data management model uniformly used in the SuperMap remote sensing and GIS integrated product system. It gives the image service excellent data management capabilities. The image service can manage multiple storage media including local file systems, shared directories, object storage, and FTP servers, and multiple formats of PB-level images. It also supports the management of primary satellite data products. The image service uses metadata to manage images. There is no need to change the original storage location of the image, and no need to store the image twice. This avoids the problem of repeated data storage caused by unified management of images stored in different positions, and solves the problem of low efficiency of image storage management. Convenient and easy-to-use image management operation SuperMap has also provided quick publishing service to improve the ease of use of data management. Based on image services, you can manage data in an efficient way on the SuperMap iServer service management page by creating an image collection and performing simple data source configuration. The data source of the collection supports a variety of configuration forms, including: image data directory, image file list, and existing mosaic data collection results. In actual business scenarios, the image management system may receive new images regularly and update them frequently. For example, the remote sensing production results data management platform will receive new results data from time to time. Managing the incremental images manually processed is indeed a lot of work. To improve such experiences, we provide the monitoring data directory and the ability to automatically add new images, which can be realized by simply turning on automatic addition during the process of configuring the data collection. At the same time, the image service also opens a data management API, which is an OpenAI application programming interface that follows the STAC (SpatioTemporal Asset Catalog, SpatioTemporal Asset Catalog) API specification. It can realize the web-end development of image service management capabilities, which is conducive to the docking of industry business systems with SuperMap iServer image service and enables convenient, efficient and unified management of images. “Efficient management and instant release”service Through the image service, you can publish image map services without slicing. Images can be dynamically mosaic-displayed and support display style configuration, which takes effect in real-time. The slice-free publishing capability of the image service can meet the needs for rapid image publishing and preview in scenarios with high frequency of data updates, rapid changes in display styles, and low concurrent visits. For scenarios with low data update frequency and high concurrent access, we also provide solutions. You can enable silent slicing of image service to generate image map tiles. When dynamic caching mode is enabled, Image Service can provide tile services, meeting the performance requirements of high concurrent access. In addition, image service silent slicing supports scheduled tasks, which makes it easy to select a time period when server resources are relatively idle and then complete slicing tasks that consume large resources. Service types for multi-scenario applications The image service provides multiple service types such as STAC API, tile, WMS, and WMTS. Among them, the tile service can return tile resources with specified row and column numbers, filter conditions and display styles to meet the filter display and real-time rendering requirements of image map services; the WMTS service can facilitate third-party client systems. The WebGL three-dimensional scene can dock with image services and become basemap service. WMTS service also supports pre-caching capabilities to ensure the rendering efficiency of image basemaps. The image service has multi-temporal image management capabilities, and the WMS service is suitable for visual display of temporal data playback. Image data retrieval and download service The imaging service provides an out-of-the-box image data retrieval page. It supports multiple query and retrieval methods, and query results previews. It also supports configuration data download, and provides retrieval result download services. In actual business scenarios, the use of more complex retrieval conditions may be required. For example, in the management of satellite data products, it may be necessary to use multiple conditions such as satellite sensor types, shooting time, cloud coverage, etc. to query target images. In this case, you can expand and develop data retrieval applications that meet business needs through the image service API, and further solve the problem of difficult data retrieval on the basis of unified management of image data. Retrieval preview of image service Opening up all image applications The above mainly introduces how image services can effectively solve many problems faced by massive image management and release in industry applications, and achieve integrated data management and service release. However, integrated full-process image applications also include data processing and other important application aspects. SuperMap iServer provides image processing GPA services and machine learning services of intelligent interpretation. These services support the ability to obtain and process data from imaging services, truly opening up the full range of image applications from data management to data processing, data applications, and intelligent interpretation. Map service for analysis results of buildings extracted from images Summary SuperMap iServer image service has the capability of convenient, efficient and unified multi-source massive images management and rapid service release, solving multiple user pain points in image management. In addition, based on the unified image data management model of the SuperMap GIS product system, SuperMap iServer image service opens up the process from image data management to application, and even has the ability to connect to other SuperMap GIS products to carry out image processing business. This helps form an application closed loop of "instant production and management, immediate management and deployment, and immediate deployment and use" of images, facilitating the implementation of integrated solutions for full-process image applications.
