A method and apparatus for detecting objects. An object detector associated with a platform and configured to detect a number of objects is used to monitor for the number of objects. In response to detecting the number of objects, a number of distances to the number of objects detected by the object detector are measured using a distance measurement system. A number of geographic locations for the number of objects is identified using the number of distances, a location of the platform, and an orientation of the distance measurement system.
