Monitoring coastal ecosystems for management decision support requires efficient tools but simple to use for managers who can be often not familiar with image analysis. In this context, sampling procedures constitute a link between expert knowledge of the study area and remote sensing data analysts, while being a crucial step for mapping accuracy. After examining sampling methods through recent papers, this course considers a basic statistical comparison of spectral responses obtained for sparse and heterogeneous developments of two salicornia species in a former Mediterranean salt marsh area in south of France, using different Quantum GIS sampling tools applied on WorldView 2 and SPOT 5 images.
