Couplage de données optiques et radars pour la caractérisation de paysages urbains amazoniens : application à l'île de Cayenne

Abstract : This paper contempts optical and radar data complementarity for the characterization and cartography of urban landscapes. Our study site, the city of Caiena, is located in French Guiana (4,56º Latitude North). Complex urban dynamics result in a significant diversity of unstable urban habitats, for which optical remote sensing does bring solutions in terms of mapping and monitoring. But because of Caiena's location, cloudless optical scenes are limited to an average of one per year. Recurrent radiometric confusions given by pixel to pixel classifications disturbs thematic mapping accuracy. In order to overcome these difficulties, we have tested methods combining optical and radar imagery.
