resolution level, it would have to be necessary to significantly reinforce the perfor-
mance of computer equipment or optimize the computing procedures.
When verifying calculated cost maps directly in the terrain, we discovered
certain drawbacks caused mainly by absence of some of the declared characteristics
of objects in the DMU25 database. However, these were mostly insignificant faults
which did not affect the total calculation result. When consulting these problems
with the provider, we were assured that the current new database edition, which we
could not use at the time of calculations, would be more complete.
On the other hand the differences between crisp set and fuzzy set analyses were
not very visible in build-up area because there were mostly objects with certain
position (building, streets etc.). Therefore the calculated coefficient will be verified
in an area outside build-up areas (in military training area) in the next phase of the
project, and the authors expect verification also with the use of various types of
military vehicles.
