Résumé

This report discusses the application of automatic cartography of vegetation by remote sensing, to part of the Cevennes National Park (France). Its execution was supervised and used two LANDSAT locations on 02-06-1978 and 06-10-1978. The study aimed to contribute to the mapping of the ecological units which form the fundamental elements of management of the National Park. A considerable number of small areas were characterized during the initial part of the study. Information of the homogeneity of ecological units was thus extracted before the classification of data. An adjustment to the thematic and spatial taxonomy produced a monotemporal cartography with 6 classes over the entire region, and a bitemporal cartography with 8 classes for a smaller part of the area observed. Evaluation of results showed a precision of identification (65%) acceptable for the type of natural environment studied. Globally, monotemporal cartography of the entire region gave areas of homogeneous appearance which would indicate areas of identical vegetation. This study demonstrates the value of a procedural model integrating the characteristics of the natural objects considered. In addition, it would appear that its repetition is particularly well adapted to the study of the development of disadvantaged regions and natural environments during transformation.
