                <gco:CharacterString>Les zones d'hydrographie de texture ont été intégrées à partir de la base PROCLAM (Cartographie du littoral amazonien réalisée par l'IRD) et du fichier recensant les zones dégradées fourni par l'ONF.  La nomenclature PROCLAM a été simplifiée selon une description hydrographique. La géométrie de cette base a été mise en cohérence avec celle de l'hydrographie de surface. Les zones dégradées fournies par la l'ONF ont été intégrées comme "Flat". Un flat correspond ici au lit majeur d'un cours d'eau qui a été dégradé, et où l'écoulement a été perturbé et n'est plus identifiable. On peut retrouver dans un flat des bassins non naturels en eau correspondants à des bassins de décantation abandonnés.  Des compléments de numérisation ont été réalisés sur la mosaïque SPOT à 2.5 m.</gco:CharacterString>
