- A stereoscopic aerial picture
- A photograph derived from a conventional perspective photograph by simple or differential rectification so that image displacements caused by camera tilt and relief of terrain are removed
- a completely rectified copy of an original photograph All variations in scale and displacements, due to relief, have been eliminated, hence the name ortho (correct) photography Orthophoto and orthophoto map are synonymous, an orthophoto is, very simply, a photomap
- A photograph of the earth's surface in which geographic distortion has been removed
- or orthoimagery - a photographic image showing features in their true plan positions Geometric and relief or height displacements have been removed
- A map product created from an aerial photograph that is free of the distortion associated with capturing the original image Supplementary information map be added such as place names, a locational grid, contour numbers, and feature (e g : buildings, roads, rivers, cutblocks) outlines
