orthophotograph

[‚ȯr·thə′fōd·ə‚graf]
(geology)
A photographic copy, prepared from a photograph formed by a perspective projection, in which the displacements due to tilt and relief have been removed.

orthophotograph

(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.

LiDAR intensity data is orthographic in nature, therefore radial displacement is not present; it also has the same spatial reference since the LiDAR surface data was used in the digital orthophoto production process.

Another common and useful tool available to GIS users through photogramme try is an image called a "digital orthophoto." A digital orthophoto is a digitized aerial photograph that has been geometrically corrected to its true map projection.
A conventional orthophoto is a photograph with images of ground features in their true map positions, similar to a vector map created photogrammetrically from aerial photography.
