The orthophoto is obtained by rectification of aerial photographs by eliminating distortions due to relief and perspective. It is very useful in many fields:
- major Infrastructure
- urban GIS
- Hydraulic studies
- Buildings / facades
- Natural Hazards and Environment
This produces a 2D document with a uniform scale geometric quality rendering superimposed on a plane or a vector type of card. Georeferenced, it is often integrated into a GIS in a standard format (TIFF / TFW, GeoTIFF, ECW / ERS ..). It describes the environnement as an image.
It is therefore particularly interesting to see the occupation and the nature of a surface.
