For the purpose of of forestation, planning and development in the Three-North Region, a series of 6 Landsat TM scenesfrom 1996 to 1997 were used to classify land-use conditions in the whole Korqin Sandy Lands at eastern part of Inner Mongolia, China, with an area of about 430×306 square kilometers. Later on, Site classiflcation was made and mapped for the 4 southern sandy counties. The annotation symbol for each agglomeration of site condition is comprised of six parts: land unit, land use pattern, soil texture, under ground water table, top-soil existence, wind erosion or salinisation condition. Field expedition and soil file augering help information extraction from the satellite imagery. The products include a land-use classiflcation map at scale 1/200,000 of the whole Korqin Sandy Lands, and a collection of site classiflcation maps at scale of 1/50,000, consisting of 135 pieces (42.8 cm×30.8 cm each). Electronic version of the maps is in raster form.
