Core Viewpoint - The Shaanxi Provincial Geographic Information Bureau has launched the 2025 version of the low-altitude economy spatiotemporal infrastructure platform, which includes three major application systems to support the development of the low-altitude economy through advanced spatial information technologies [1][2]. Group 1: Platform Overview - The 2025 version of the Shaanxi Geospatial Big Data Comprehensive Service Platform includes the "Sanqin Image" 3D real scene platform, Beidou navigation positioning service platform, and satellite remote sensing data service platform [1]. - The platform aims to achieve precise perception and dynamic management of the low-altitude world, providing core driving forces for the development of the low-altitude economy [1]. Group 2: Application Systems - The "Sanqin Image" platform integrates multi-source, multi-scale, and multi-type 3D data to create a unified 3D spatiotemporal data foundation for Shaanxi, enabling comprehensive digital modeling and management of low-altitude elements [1]. - The Beidou navigation positioning service platform offers centimeter to millimeter-level positioning accuracy, supporting low-altitude flight with a high-precision positioning service network across provinces [2]. - The satellite remote sensing data service platform provides real-time remote sensing imagery, covering the entire province with better than 2-meter resolution every two months and better than 1-meter resolution every six months [2]. Group 3: Future Development - The Shaanxi Provincial Geographic Information Bureau plans to enhance the construction of new spatiotemporal information infrastructure and improve the supply capacity of geographic information data elements [2]. - The focus will be on building a low-altitude economic ecosystem, deepening application demonstrations, strengthening key technology research, and promoting the standardization of spatiotemporal information [2].
