Some points were used as training samples to perform image classification without photo-interpretation errors, and others were used to validate the results. The typology of land cover classes was developed with the help of ecologists familiar with the different genera present in the studied salt marsh. To carry out the survey, the salt marsh was traversed following random transects and different orientations. 387 points were surveyed with a SP80 DGPS by Maxime Paschal as part of the La Rochelle Zero Carbon Territory (LRTZC) project on 26/05/23.
