Summary/Abstract: Term “availability” is most often understood as easiness of achieving a site or a services from other places which can be measured as e. g. distance, travel costs or time duration. Despite of broad usage, distance calculating is often methodically incorrect because it takes place in two-dimensional environment. This causes distortion of results which are in fact threedimensional. In our paper we focus on calculating real spatial and time distance with considering a fact that real world is not two-dimensional and terrain has often many characteristics and terrain roughness. Calculations are made on road network and hiking trails in High Tatras Mountains by use of our own tool which uses functions of GRASS GIS software. Final map layers are described and overlaid with services, tourist places of interest and phenomena of High Tatras Mountains.
