Description The content of this paper refers to the modelling of the geographic environment impact on the off-road vehicles movement in raster format. The common influences of relief slope, micro-relief forms, soils, vegetation, hydrology, built-up areas, meteorological factors, etc. on the vehicle speed deceleration are calculated. To determine the impact of various geographic environment types on the vehicle movement, many field tests and laboratory analysis were provided using military and rescue vehicles. Modelling principle of cross-country vehicle mobility in raster format is based on the idea that each geographic factor "F" located at given elementary terrain area and affecting vehicle speed has its own value of deceleration coefficient Ci. The value of this coefficient expresses the fact of how many times (or percent) a certain geographic factor will decelerate the vehicle speed. The final vehicle deceleration is calculated using synthesis of corresponding raster cells in elementary terrain area in which the influences of geographic factors on vehicle speed are constant. The ArcGIS software suite was used for building the cross-country movement (CCM) database and constructing the CCM map. The database, which has been developed for selected vehicles by the Military Geographical Service of the Czech Armed Forces, should serve as a military geographical support tool during the military and civil operations to improve vehicle navigation.
