Orthophotography is a geometrically corrected aerial photograph (ortorectified). Unlike an aerial image, an orthophoto can be used to make real measurements since it is an accurate representation of the earth’s surface, in which the distortions inherent in aerial images have been corrected. Orthophotos combine the detail and temporal coverage characteristics of aerial photographs and the uniform scale and geometric accuracy of the maps.
Dates: High flight (135, 1:25,000). 28/01/2009 to 30/05/2009.
