Required implementation of geofactors of rock workability and prequaternary base type into land-use planning

Abstract

The current technological means in geographic information systems bring new possibilities of implementation of important natural conditions into land-use planning. The paper focuses on two such geofactors, i.e. workability of rocks and Prequaternary base, which are very important for future foundation engineering. At the same time, the study presents the form through which it is possible to provide the information to authorized offices and developers, namely using analyses of the factors through geographic information systems. This helps to determine areas with specified conditions in terms of the geofactors in question and the relevant authorities may be able to provide the information to future developers or may take it in consideration during decision-making on future land use. The studied area (model area 2, determined by a topographic map 15-43-05 in 1:10 000 scale) is located in Ostrava, the third largest city agglomeration in the north-east of the Czech Republic (city districts of Slezská Ostrava, Moravská Ostrava, Přívoz and Petřkovice), which is however most affected of all Czech cities as well as cities in the European scale by anthropogenic industrial and mining activities.
