The paper deals with an evaluation of four selected geobarriers (flood lands, radon hazard, undermining and slope movements) by means of geographic information systems that are geofactors endangering or limiting landscape and environment or make certain land use impossible. The objective is to improve the possibilities of their implementation in land use planning. The research was carried out in the area numbered 4, which is one out of five realized model areas in the future. It is located in Ostrava, the third largest agglomeration in the north-west of the Czech Republic, which has been most affected by anthropogenic industrial and mining activities among the Czech cities as well as in the European scope. The area is defined by a map sheet 15-43-09 in the town districts of Mariánské Hory a Hulváky, Nová Ves, Svinov, Třebovice, Hošťálkovice, Moravská Ostrava a Přívoz, Ostrava – Jih and Vítkovice
