FIELD: radio engineering, communication.
SUBSTANCE: method of determining the probability of exiting an area identified on a digital map as open terrain, starting from a position within the area, includes dividing the area into a plurality of cells, with an initial transition probability being assigned to one transition from one cell to an adjacent cell, between the position and the edge of the area; adjusting the initial transition probability, performed in the presence of a type of information from the digital map relating to a cell or adjacent cell to obtain an adjusted transition probability and determining the exit probability, performed using the adjusted transition probability. The invention also relates to an apparatus for determining the probability of exiting an area according to said method.
EFFECT: faster determination or plotting of a route.
