Applying geomathics to determination of landscape altitudinal zones in the mountains

The paper presents a method enabling determination of the extent of landscape zones, based on the criterion of area coverage by vegetation. This method made it possible to objectively determine the extent of landscape zones both in the entire Tatra Mts. and in their particular parts. The altitude, at which dominant type of vegetation changes, is considered to mark the boundary of a landscape zone. Boundaries distinguished in this way in the Tatra Mts. are presently situated at: 1,510 m a.s.l. (forest zone), 1,730 m a.s.l. (subalpine zone), and 1,880 m a.s.l. (alpine zone).
