Terrain Mobility Model and Determination of Optimal Off-Road Route

The paper describes a concept for GIS based terrain mobility modelling and optimization of off-road route. The concept of generation of cost surface is based on machine, terrain, tree coverage, road and weather objects. Different cost surface alternatives can be generated according to changing information in objects. A regular costpath analysis is used to determine alternative routes in different conditions. It has been shown that adequate number of useful parameters can be found from national level digital maps for supporting offroad analysis.
