Description
An orthophoto is a geometrically corrected aerial photograph. It is generated when the effects of tilt and terrain relief are removed from the aerial photograph by a process called orthophoto rectification, allowing for ground features to be displayed in their true ground position. This allows for the direct measurement of distances, areas, and positions (if printed at scale or used in a Geographic Information System). An orthophoto may serve as a base layer onto which other map information may be placed over. When two or more orthophotos are merged or mosaiced together then clipped to a specific area, an orthophotomap is created.
