Application of the digital terrain model in spatial analysis

Digitalni model reljefa je, najjednostavnije rečeno, statistički prikaz kontinuiranih površina reljefa (u vektorskom ili rasterskom obliku) s nizom poznatih x, y i z koordinata unutar proizvoljno odabranog koordinatnog sustava (Millner i Laflamme, 1958). Različiti su izvori podataka za izradu digitalnog modela reljefa: od terenske izmjere, digitalizacije izohipsi, daljinska istraživanja. Digitalni model reljefa predstavlja kvalitetnu podlogu pri analizi prostora, a u ovom diplomskom radu su prikazane: metode izrade DMR-a, načini prikupljanja podataka za izradu DMR-a, derivati iz DMR-a (nagib terena, izloženost, ...) pomoću kojih je moguće provoditi različite prostorne analize u GIS-u.A digital relief model is, in the simplest terms, a statistical representation of continuous relief surfaces (in vector or raster form) with a series of known x, y and z coordinates within an arbitrarily chosen coordinate system (Millner and Laflamme, 1958). There are various sources of data for the creation of a digital relief model: from field surveying, digitalization of isohypsis, remote surveys. The digital relief model represents a high-quality basis for the analysis of space, and in this thesis the following are presented: methods of creating DMR, ways of collecting data for creating DMR, derivatives from DMR (terrain slope, exposure, ...) with which it is possible to carry out different spatial analyzes in GIS
