Photogrammetry is the art and science of using photographs to measure objects which cannot be touched directly. It is primarily used for creating maps from photographs of the Earth. Photogrammetry companies frequently also take the aerial photographs, and sometimes also provide land surveying or other related services.
Submit sites to this category if the organization provides photogrammetric mapping or vertical aerial photography for mapping, or a directly related service. Note other services provided briefly. The service is unavoidably local; a brief note of the location is useful. Organizations who primarily provide aerial photography of a pictorial or illustrative nature go in Business: Arts and Entertainment: Photography: Photographers: Aerial.
