Orthophotography

An orthophotograph is a two dimensional projection of a high density point cloud – an orthographic planar projection. While they appear to be photographs, they behave much more like drawings – as elevations or plans drawings – as they describe the real size, shape and layout of as structure in architectural terms.

Orthophotos are unlike photographs in that they do not originate from a single point of view (such as a camera station) but are created as a planar projection of three dimensional points. They are similar to photographs in that they are composed of pixels colored to match the surface described.
