Abstract Recent advances in computer vision have enabled the automatic recovery of camera and scene geometry from large collections of photographs and videos. Such three-dimensional imagery reconstructions may be georegistered with maps based upon ladar, geographic information system, and/or GPS data. Once 3D frameworks for analyzing two-dimensional digital pictures are established, high-level knowledge readily propagates among data products collected at different times, places, and perspectives. We demonstrate geometry-based exploitation for several imagery applications of importance to the defense and intelligence communities: perimeter surveillance via a single stationary camera, rural
