AIRBORNE MUTIPLE SPECTRA SCANNING IMAGES APPLIED IN LAND INVESTIGATION IN DONAUESCHINGEN AREA, WEST GERMANY

The feasibility and limitations of air-borne mutiple spectra scanning images applied in land-use investigation are approached. The establishment of classification system for land-use,the correlation of images of different bands to different targets, the process of monitoring classification, statis tical evaluation of classifying presision for the study area are discussed respectively. According to the pratical needs of land-use classification in the study area, two bands are chosen from original 11-band images, and applied in automatic classification with the desired results come about. The results show that airborne multiple spectra scanning images have both advantages of aerophotos and salellite images, which will give higher resolution as well as make digit image processing with the aid of computer. It can be also regarded as an effective measure of remote sensing in land-use investigation. But due to the unstability of image forming platform, the reliability of image formation and results of investigation are often affected, which limited its wide use in land-use investigation.
