Ortho-rectification

Ortho-rectification 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 does all of our ortho-photo production in-house, and provides very fast turnaround times for most projects.
