A system and method for generating a 3D model and/or map of a geographic region is disclosed. A computer designates a geographic region and a number of aircraft, and partitions the designated geographic region into sub-regions, creates waypoints within each sub-region, and plans missions for each aircraft to fly to each waypoint and take pictures. The aircraft are configured to accept and perform missions from the computer, and the computer receives images from the aircraft, assigns each image to a sub-region, and transmits each sub-region and images, as well as instructions, to the computing resource. The computing resource executes the instructions, which perform 3D reconstruction and generate orthophotos and 3D models. The 3D reconstruction comprises trimming distorted portions of the orthophotos and 3D models, and merging the orthophotos and 3D models from each sub-region into a 3D model and/or map of the geographic region.
