The aim of this project was to create a cumulative visibility raster (find out viewshed information for every point) and characterize visibility over the entire terrain surface. Creation of cumulative visibility raster is very time consuming and hardware-demanding. Within high-performance computation, the analysis was calculated by parallel process...

A fundamental tool for the exploration of the relations (dependencies) among two or more variables is a correlation analysis. Main goal of the correlation is to analyse an existence or absence of the relation among chosen variables and also quantification of the strength of this (in)dependence. A dependent variable as well as an independent variabl...

The topic of the conference paper is aimed to the detection and quantification of the landscape changes identified from the aerial photos, reconstruction maps and actual land-use. It includes also the description of the quality and structure based on landscape indexes in a given stage and appoints at the main causes of the changes in the landscape...

Computer models of spatial phenomena mostly use Digital Relief Models (DRM) (morphometric characteristics, drainage situation, etc.) to represent the earth’s surface and its properties. The definition of the term digital model of relief is currently inconsistent both in Czech and in foreign professional literature (e.g. Šíma 2002; Voženílek 2001; K...

The article deals with an evaluation of the digital elevation model accuracy as theoretically as practi- cally. The general processes of evaluation of the accuracy and the practical results obtained by the com- puting of digital elevation models and theire evaluation on the test areas are presented in this text. The results of the evaluation of acc...
