Abstract

Cilj je ovog rada ispitati primjenjivost metoda klasifikacije reljefnih oblika iz podataka digitalnog modela reljefa u geomorfološkom kartiranju. Testirat će se metoda Indeksa Topografskog Položaja (Topographic Position Index-TPI). Tom se metodom na temelju svog položaja klasificiraju ćelije rastera u reljefne oblike. Metoda TPI-a je primijenjena ekstenzijom kompatibilnom s ArcGIS 10 programskim sustavom. Na temelju vrijednosti DMR-a primjenom metode TPI izdvojeni su grebeni i doline na području geomorfološke regije gorske skupine Ćićarije s Učkom. Za potrebe usporedbe dobivenih rezultata, na temelju izohipsa iz topografskih karata mjerila 1:25 000, iscrtani su grebeni i doline. Također na temelju DMR-a primjenom hidroloških funkcija izdvojeni su grebeni i doline. Analizom svih parametara i postupaka klasifikacije reljefa metodom TPI-a prepoznate su prednosti i nedostatci za različite tipove terena i različite potrebe analiza. Istraživanje je izvršeno primjenom ArcGIS 10 programskog sustava.

Abstract (english)

This thesis aims to examine the applicability of the classification of relief forms based on digital elevation models in geomorphological mapping. The thesis will test the Topographic Position Index-TPI method. This method classifies the cells of a raster based on their position into relief forms. The TPI method is applied with the extension that is compatible with ArcGIS 10 system. In the geomorphological area of the mountain range Ćićarija and Učka, ridges and valleys are classified based on DEM cell values. In order to compare the results, based on the contours from topographic maps in scale of 1:25000, cliffs and valleys are drawn out. Furthermore, based on DEM using hydrological functions valleys and ridges are derived. Analyzing all the parameters and types of classification available in the TPI method, this thesis shows advantages and disadvantages for different relief types and analysis. For all the digital analyses computed in this thesis ArcGIS 10 system was used.
