MOUNTAINS’ PEAKS DETERMINATION SUPPORTED WITH SHAPES ANALYSIS

Tomaž PODOBNIKAR

ABSTRACT: Peaks determination is commonly applied subjectively and manually by mountaineers. The key issue of the paper is to develop the automated methods for points of regional peaks detection applying spatial analysis on digital terrain model (DTM). Detection of the peaks bases on measurements of relative heights and distances between the peaks with support of potential surfaces fulfilling topographic and morphologic criteria. The quality of the results has been proved in the following ways: visually, with the reference lists of peaks, and triangulated spot heights on the topographic maps. The advantage of the proposed automated approaches is higher comparability, objectivity and reliability of the results. A consistent result may be attained using a DTM of high geomorphological quality and robust methods. The proposed methods can be used for more reliable and graphically better cartographic presentations. The study was applied for the Kamnik Alps, Slovenia.

Keywords: Peaks/summits, DTM, morphometry, morphology.
