The volcanic origin island covers an area of more than 2500km² and is the largest island in the Mascarene archipelago.

The methodology uses a Very High Spatial Resolution image (Spot6/7 or Pleiades) and one or more time series of High Spatial Resolution optical images such as Sentinel-2 and Landsat-8 for a classification combining segmentation and object classification (using the Random Forest algorithm) trained by a learning database combining in situ collection and photo-interpretation.
Within Theia Land Cover SEC, TETIS CIRAD team has developed an automated soil mapping system for Reunion Island, based on the Moringa chain, which minimises user interaction by automating most of the image analysis and processing.
