Digital terrain models as topographic layouts for civil engineering design

Abstract

The concept and the production of Digital Terrain Models (DTM) has drawn a lot of attention of spatial data users. In addition to numerous improvements that were made in data collection technologies, big market with wide diapason of DTMs products was established. For this reason, it is necessary to develop methods and procedures that would enable quality assessment of these data bases. In this paper the review of contemporary spatial data acquisition technologies for DTM production is given, as well as the possibilities of usage of DTM, especially in civil engineering applications.

Koncept i tehnologija izrade digitalnih modela terena (DMT) poslednjih godina sve više zaokuplja pažnju mnogobrojnih korisnika ovakve vrste prostornih podataka. Osim što je načinjen veliki pomak u pojavi novih tehnologija za prikupljanje podataka na terenu koje su omogućile dobijanje visoko kvalitetnih baza podataka o reljefu, formirano je i tržište na kojem se nudi široka lepeza ovakvih proizvoda. Ovakve baze podataka zahtevaju i razvoj metoda i postupaka koji će omogućiti ocenu njihovog kvaliteta. U radu je dat osvrt na savremene tehnologije prikupljanja podataka za potrebe izrade DMT-a, kao i mogućnosti korišćenja ovakvih proizvoda s aspekta njihovog kvaliteta, i s posebnim osvrtom na primenu DMT-a u građevinarstvu.
