French Guiana landform map 2012
This landform 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. Classes correspond to different types of landforms. Taking into account data accuracy, we recommend using the landform map for scales beyond 1: 100 000 to 1: 250 000. The map was produced at the request of the French Guianan public forest manager of the Office National des Forêts (ONF).

- Statement
- Derived digital elevation model (DEM) was used as a digital terrain model (DTM). The entire territory was segmented into 224 000 landform units on the basis of an original object-focused approach (Cornu et al., in prep). Map was compared to topographic field data that have been collected on 92 transects totalizing 260 km length. These data including natural habitat descriptions, topographic profiles, and soil collections were collected on 24 sites distributed through French Guiana in order to represent the maximum of geographic and ecological variability. Habitat descriptions are used to validate the hydromorphy model. Slope. elevation levels and topographic position occurrence measured on the transect help to interpret landforms and landscape classes. A Garmin GPS (60CSX) was used to geolocalize the data. Slope angles and distances were measured with Vertex laser rangefinder.
