Abstract: Techniques are disclosed for assigning a geographical location to a photograph of a landscape. A geographic location tag is calculated from raw sensor data and a three-dimensional terrain map that corresponds to the landscape in the photograph. One technique includes calculating a two-dimensional ideal view projection of a camera used to take the landscape photograph based at least in part on a geographic location of the camera when the landscape photograph was taken and a field of view of the camera when the landscape photograph was taken. At least one of the topographical features visible from the camera based on the two-dimensional ideal view projection is selected from a three-dimensional terrain map representing a plurality of topographical features within a geographic region. At least one geographic location tag representing at least one of the selected topographical features is assigned to the landscape photograph.
