Ortho-rectifiation is a process that uses multiple overlapping vertical aerial photographs of an area to create an ortho-photo. Using these overlapping photographs, common points are triangulated and a 3D model of the terrain is created. This 3D model, in combination with survey data and aircraft GPS data, is used to create an accurate map of the scene.
Ortho-photos are the foundation of maps used in Geographic Information Systems (GIS) including Google Earth.
Focal Flight accomplishes all of our ortho-photo production in-house, and can provide very fast turn around times for most projects.
