A photograph prepared from a perspective photograph by removing distortions and displacements of points caused by tilt, relief, and perspective.
An aerial photograph that has the distortion due to tilt, curvature, and ground relief corrected.
Aerial photograph having properties of an orthographic projection. Orthophotograph is derived from a regular photograph which has been processed to have displacement and distortion removed (caused by camera tilt and terrain). Orthophotographic map is a mosaic of orthophotographs all at the same scale.
an aerial photograph that has been orthorectified to remove displacement caused by aircraft movement, photographic tilt, curvature of the earth, and changes in topography
an aerial photograph with nearly all the image displacement and scale errors removed
Aerial photograph that corrects distortion caused by tilt, curvature, and ground relief.
Photograph having the properties of an orthographic projection. It is derived from a conventional perspective photograph by simple or differential rectification so that image displacements caused by camera tilt and terrain relief are removed.
A photographic reproduction in which each image has been extrapolated into its map-oriented (orthographic project) position.
An aerial photograph that has had all the distortions due to camera tilt and surface relief removed. An orthophoto has the advantages of a photograph (all visible features displayed) and the constant scale and accuracy of a map.
An orthophotograph is a photograph that has been re-assembled to function as a true map. The typical orthophoto is produced from aerial photography that has been differentially rectified (the photograph has been altered to remove both distortions caused by terrain relief and the tilt of the camera at the instant the film was exposed). Orthophotos combine the image characteristics of a photograph with the geometric qualities of a map.
An aerial photograph that has been scanned, rectified, reconstructed, and projected so distortions of geometry and perspective are removed. Also called an orthophoto.
An aerial photograph in which the displacement of images have been removed and may also form the base map for many GIS programs
