Abstract: Efficient 3D geospatial mapping is disclosed. A 3D geospatial map of an area of interest is generated from 2D satellite imagery. The 2D imagery is preprocessed to generate a point cloud of the area of interest. The point cloud is optimized by removing atmospheric clouds and shadows. A 3D geographical information system (GIS) map with multiple levels of details (LOD) is generated.
