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).

The aerial laser scanning (ALS) dataset, acquired in October 2004, covers five plots of Crique Plomb and Montagne Plomb area in French Guiana. In this area. the forest presents contrasting and diversified characteristics : high forest, forest grown on ferricrust, and superficial saprolit with high density of stem per hectare. Ground echoes are available as well as a digital terrain model (DTM), a digital surface model (DSM), and a digital canopy model (DCM) with a 1 meter resolution.
