These tests emphasize the great potential of this type of vector to produce low-cost images with a very high resolution. This study demonstrates that these products can be used in rough landscapes and areas that are hard to reach such as badlands. They are well adapted for high-scale and highly repetitive mapping on small experimental catchments such as those found at the Draix observatory. They are of great interest in the study of erosion issues because they provide a link between the local-scale survey (ground data) and the traditional remote sensing survey (aerial photograph or satellite). Such products can thus help further the understanding of hydrological measurements at the catchment's outlet.
