It is based on 2D & 3D integrated GIS technology, further develops the computing and analysis capabilities of geospatial data model, combines oblique photogrammetry, BIM, point cloud, 3D field and other multi-sourced heterogeneous data, and sets an open "Geospatial 3D Model Data Format" (S3M) standard and "Geopatial 3D model data service interface" standard to support GIS standard system. Based on distributed technology, the efficient whole-process management of real-time 3D data such as oblique photogrammetry model and point cloud can be realized. It integrates IT technologies of WebGL, VR, AR, AI, 3D printing and etc. to bring a more realistic and convenient 3D experience, promote 3D GIS to achieve outdoor and indoor integration, macro and micro integration, and aerospace/surface/underground integration, and empower the application of full space new 3D GIS.
