Photogrammetry and types of photographs:
Photogrammetry is an art or science of preparation of maps, plans, or 3D models of areas, using the photographs taken by the photogrammetric cameras. It is broadly classified into two categories,
(1) Terrestrial Photogrammetry  (2) Aerial Photogrammetry
In Terrestrial photogrammetry the photos are taken on the surface of the earth, and these photos are used to interpret the 3D models, or the dimensions of the objects. Terrestrial photogrammetr…
