Modelling of the microrelief impact to the cross country movement

Ground maneuver in natural environment is usually limited by a number of obstacles called micro relief, which are defined as man-made and natural both elevated and depressed topographic forms that cannot be expressed with regard to its relative small height differences. This terrain feature is present almost in all types of environment and extend the “off-road” path in average about certain coefficient, dependent on the type of the area. This extension should be taken in account in particular planning and decision making process tighten to a “just in time” concept, widely present for example in the operational environment. The aim of the article is to describe the methodology of evaluation of the influence of micro-relief shapes on the mobility of military vehicles. The article is based on the statistical determination of the extent of micro-relief shapes in the territory of the Czech Republic
