Flight Area Zorita de los Canes - Spain Geo Referenced Satellite Image Base Map Flight Plan The Flight Plan was used three times for: 1. Multispectral Flight 2. Video Flight 3. Photo Flight for 3D Model
Collecting Ground Control Points - GCPs + + The Orthophoto is measured in with Ground GPS, which provides GCPs Ground Control Points. With those GCPs we geo - reference the Orthophoto and we enhance it with a GEO GRID. Note: Without Reference Image and without GCPs you cannot measure correctly and this is what you definetley need!
