Land planning is more and more understood to be a decisive tool, by means of which the society secures the systematic solving of functional, economic and engineering problems of the arrangement of landscape settlement, the rational use and protection of natural resources. 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 ...

The basic precondition for town planning, foundation engineering in a certain area is the integrated knowledge of engineering-geological conditions that form a decisive factor for good-quality and functional foundation of potential structures. Research was carried out into a chosen model research area in the part of Ostrava-Karvina Coalfield with various characters of foundation soils, with significant influencing by anthropogenic and other geodynamic processes and geofactors, with a possibility of future applying...

Several soft-programs to reverse tomography data acquired on 2D panels, for transmitted seismic rays, were developed. The procedures are based on three concepts: graphic mediation of velocities (V) coupled with a system of correction factors to reconstruct the initial V distribution (Tomography Interactive Modeling-TIM), minimize velocities errors by applying matrix calculation (Matrix Calculus in Tomography -MCT) and graphic-analytical uncover of velocities from the periphery to the center of the examined panel (...
