According to image rotation algorithm and the definition rule for geographic coordinate of images,the real-time reproduction with coordinate for geospatial scene on 3D GIS with flexible visual angle was realized by means of 3D GIS platform Skyline and open source tool GDAL,which takes advantages of 3D visualization and 2D analysis. The experimental result shows the proposed algorithm is suitable for geospatial scene real-time reproduction with coordinate and accurate positioning. It incar-nates advantages of integration of GIS and RS,and integration of 2D and 3D GIS,which promote the application of 3D geospa-tial information.
