The land use investigation scaled 1:100

000 in Dangxiong county

Tibet has been Completed after efforts of 11 months. In the investigation multi-seasonal Landsat MSS images for which accurate geometric correction and image enhancement were made by IRSA-2 computer image processing system and black-white panchromatic aerial photographs were used as basic survey data. In the investigation the land use synthetical interpretation key table of the multi-seasonal Landsat MSS false color composite images and aerial photographs was established

the whole programs of IBM PC/AT computer that processed land acreage measurement data were completed

and a series of technical problems in the phase of indoor work were solved.The resulte proved that remote sensing method can get higher accuracy and better economic benefit than conventional method.
