An unmanned aerial vehicle (UAV) or unmanned surface vessels (USV) collect electro-optical images, LiDAR or sonar to create a three-dimensional (3D) point cloud referenced to a geodetic datum. The resulting point cloud is a digital surface representation of the earth's surface. The process of the geospatial cleaning and point cloud compression entails cleaning of the point-cloud surface and to the automated extraction of a set of 3D vector polylines and mass points. The resultant electronic file retains the details of the bare-earth point-cloud with an approximate 10x compression in file size or more.
