Orthophoto

Orthorectification is the process of rectifying the aerial imagery as per the real world terrain model by removing the distortions caused by noise, camera and terrain relief. The rectification’s accuracy depends on the density and accuracy of the Ground Control Points and the accuracy of the DTM (Digital Terrain Model). ALG’s photogrammetry team is well experienced in generating accurate orthophotos that are geometrically correct and rectified.
