Анотация: Some approaches to the land cover mapping for agro-ecological assessment of lands are considered. For this purpose two algorithms for automated geoimage processing are compared: that of iSoDaTa and the algorithm for Уobject-oriented approachФ by program complex EnVi. according to the research results the most reliable maps are made by the second algorithm. By implementing this algorithm the objects of the vegetation cover, overwet and arable lands are clearly identified, that allows for agro-ecological land groups mapping
