This landscape dataset was built using Shuttle Radar Topography Mission (SRTM) data with full resolution (1 arc sec ~ 30m). This map aims at evaluating the geodiversity of natural areas. Twelve landscape types into 5 main categories have been identied with respect to Migon's typology (2006): the coastal plains landscapes (AA. AB. AC); the typical multi-convex landscapes (B. I. J); the multi-concave and joint-valley landscapes (C.D); the more or less dissected plateau (E.F.G) and the all-slopes topography (H). The map was produced at the request of the French Guianan public forest manager of the Office National des Forêts (ONF).
