Orthophotograph definition
(Data West Research Agency definition: see GIS glossary.) An aerial photograph in which the displacement of images has been removed and that has the distortion due to tilt, curvature, and ground relief corrected. It is a "scale corrected" aerial image, depicting ground features in their exact ground positions, in which distortion caused by camera and flight characteristics and relief displacement have been removed using photogrammetric techniques.
An aerial photograph that has been geometrically corrected (orthorectified) such that the scale of the photograph is uniform, meaning that the photo can be considered equivalent to a map.
