AbstractAfter the Soviet Union dissolved, Ukraine became responsible for territories contaminated as a result of the Chernobyl Nuclear Power Plant explosion. Base maps on which soils, land use, land cover, and farm limits are identified and delineated became necessary to support decision-making dealing with the consequences of the Chernobyl disaster. Satellite imagery was used to produce such maps. IRS panchromatic and SPOT panchromatic and multispectral images were compared. Two geometric correction methods, polynomial modeling and orthorectification using a mean elevation datum, were analysed. The thematic content of the three types of images was also evaluated. Results show that panchromatic images are suitable as a stand-alone product to create a geographic database and to provide basic land cover information and IRS images are recommended because of their higher resolution.
