Intérêt du traitement de données spatialisées pour la géographie de littoral.
Résumé
Since twenty years, remote sensing data provide a new approach for tidal flat studies. A processing of satellite data series makes easier the study of coastal evolution but superposition and crossing of satellite imagery integrated into the GIS allow a parameter extraction and a modelization of phenomena. This paper suggests a spatial model of emersion rate based on hypsometric data and processing of Landsat pictures integrated into a GIS.
