Digital analysis of the slopes of Rab Island

U radu su analizirana morfometrijska obilježja padina otoka Raba. Na temelju formiranoga digitalnog modela reljefa izračunati su rasterski slojevi vrijednosti nagiba, ekspozicije i zakrivljenosti padina, te dolinska mreža koja je grupirana prema metodi Strahela. U GIS okružju provedena je međusobna analiza izračunatih vrijednosti morfometrijskih parametara. Prostorni raspored vrijednosti pojedinih morfometrijskih parametara doveden je u vezu sa strukturnim i morfogenetskim obilježjima otoka Raba. Utvrđene su razlike obilježja padina unutar pojedinih morfogenetskih tipova reljefa, kako na temelju samih morfometrijskih obilježja, tako i analizom dolinske mreže.The paper analyzes morphometric features of the slopes of Rab Island. Based on the digital elevation model, raster layers were calculated for the values of slope angle, aspect and curvature, as well as valley network, which was grouped using the Strahler method. A comparative analysis of the calculated values of morphometric parameters was conducted in the GIS environment. Spatial distribution of the values of each of the morphometric parameters was correlated to the structural and morphogenetic features of Rab Island. Differences between the slopes features within each of the morphogenetic types of the terrain were ascertained by comparing their morphometric features, and by using the valley network analysis
