Orthomosaics

Orthomosaics correspond to an assembly of aerial photographs in which image rectification is carried out at ground level only. All objects above ground level (buildings, poles, trees, etc.) are not rectified.

Rectification is used to correct scale for differences in terrain elevation, image distortion due to lens deformation and perspective due to fields of view.
