摘要：
REMOTE SENSING INVOLVES AERIAL AND SPACE SURVEYING TO STUDYTHE COMPOSITION, STRUCTURE, PHENOLOGY, AND DYNAMICS OF RANGELANDS. THE LANDSCAPE APPROACH TO RANGELAND SURVEY IS CONSIDERED AT VARIOUS SCALE LEVELS - FROM THE DETAILED (POPULATION) AND ELEMENTARY (BIOGEOCENOTIC) TO LOCAL AND REGIONAL LEVELS. CHANGES IN RANGELANDS DUE TO OVERGRAZING CAN BE MOST SUCCESSFULLY DETECTED BY COMPARING SUCCESSIVE AERIAL AND SPACE PHOTOS OF THE SAME AREA, AND BY RECORDING LAND USE MODIFICATIONS FROM AERIAL AND SPACE PHOTOS TAKEN DURING THE SAME OVERPASS, USING OVERGRAZING AND DESERTIFICATION KEYS TO INTERPRETATION.
