Example : Landsat TM image processing

Channels are corrected from radiometric and topographic effects

• Atmospheric corrections Thanks to the Model 5S software. It is a software realised by the atmospheric optic laboratory of Lille (France)
• Topographic corrections (With the Digital Elevation Model)

The TM4 channel before (left) the atmospheric and topographic correction. One can see the shadow effects due to the relief

The TM4 channel after corrections (right). The shadow effects have disappeared
