What is Orthorectified?
Orthorectified photography is vertical photography which has been corrected so that it is true to scale and distortion free.
Generally photography is described as "vertical" - meaning looking directly down from above - or "oblique" - such as you would see looking out from an aircraft window with the foreground in good detail, training off to the horizon.
Plateau Images takes vertical photography and then drapes this imagery over a 3D model of the earth (Digital Terrain Model - or DTM) to remove any distortions from the shape of the earth and any camera defects or aircraft movements. This image is then tied to accurate survey points on the earth so that the final photographs are able to be used to measure and scale features quite accurately with real world coordinates.
Orthorectified photographs are used for a multitude of applications including town planning, environmental studies, engineering works, farm management and so on. The list is endless.
