Derivation of vegetative variables from a LANDSAT TM image for modelling soil erosion

Auteur :

Description :
A study was carried out to assess the potential use of satellite thematic mapper (TM) images to produce maps of vegetation-related variables for erosion modelling. In a Mediterranean study area in southern France (Ardèche) the (semi-)natural vegetation was described at 33 field plots using four quantitative methods. After radiometric correction of the image, the spectral TM bands were processed following three different methods. A conclusion is that a balance has to be found between the more accurate, but time-consuming field surveys to gather information on erosion-controlling factors and a loss of accuracy with the use of quick remote sensing methods.
