Abstract

JRC's present research activities on remote sensing applications are directed to evaluate the respective suitability of Thematic Mapper and SPOT data. The study area is the Ardeche department. It covers ca. 560,000 ha of extremely difficult landscape types within the transition zone from central European to submediterranean regions. Due to its climatic, morphologic and agroeconomic heterogeneity a subdivision into subregions, was considered indispensable. The spatial zoning was based on map evaluation, ground examinations, meteorological data and a visual interpretation of Thematic Mapper imagery. Each of the resulting agrophysical units was subsequently analyzed by means of automatic classification techniques. The main agricultural regions (EArdeche), which in 1984 have been covered by four TM scenes between April and August, were analyzed multitemporally whereas land cover in the mountainous and forested part of the department (W Ardeche) was mapped with reference to the only available TM dataset from early July. Based on the classification results cover statistics were calculated for eight comprehensive classes. Conclusions are discussed with respect to sensor characteristics and the spatial structure of the test region.
