Abstract

Na topografskih kartah se za prikaz reliefa uporabljajo plastnice. Včasih so jih kartografi izdelovali ročno, dandanes njihovo izdelavo omogočajo številna programska orodja. Za manj razgiban teren so rezultati modeliranj lahko sprejemljivi, vendar pogosto neustrezni za modeliranje zahtevnega kraškega reliefa. Poiskali smo optimalen modela višin in primerjali rezultate omenjenih orodij, med slednjimi smo izbrali tistega, ki je najbolj podoben prikazu reliefa na izbrani topografski karti. Z uporabo izbranega programskega jezika smo prikaz nadgradili, da se v čim večji meri približa poteku plastnic, prikazanih na državnih topografskih kartah. Izdelan algoritem smo testirali na štirih izbranih območjih.

Secondary title: Upgrade of existing algorithms for creating contour lines on topographic maps of the karst surface
Secondary abstract: On topographic maps, contour lines are used to show the relief. In the past they were made analogously whereas nowadays they can be generated by various software tools. For less varied relief, modelling results are acceptable, but often unsuitable for modelling demanding karst relief. We have found the optimal choice of the elevation model and compared the results of the above-mentioned tools. Among the latter we have chosen the one that most closely resembles the relief on the selected topographic map. The aim was to improve it by using the chosen programming language in order to get as close as possible to the course of the lines shown on the national topographic maps. The developed algorithm was tested in four selected areas.
