Application of remote sensing methods and GIS in erosive process investigations

Abstract

Modern geomorphologic investigations of condition and change of the intensity of erosive process should be based on application of remote sensing methods which are based on processing of aerial and satellite photographs. Using of these methods is very important because it enables good possibilities for realizing regional relations of the investigated phenomenon, as well as the estimate of spatial and temporal variability of all physical-geographical and anthropogenic factors influencing given process. Realizing process of land erosion, on the whole, is only possible by creating universal data base, as well as by using of appropriate software, more exactly by establishing uniform information system. Geographical information system, as the most effective one, the most complex and the most integral system of information about the space enables unification as well as analytical and synthetically processing of all data.

Geografski informacioni sistemi pružaju nam širok raspon mogućnosti analize i sinteze, koje se mogu upotrebljavati na različite načine. Analitičke mogućnosti ovako formirane baze podataka organizovane su tako da se svaka vrsta analize jednog parametra može izvesti ili zasebno ili u kombinaciji sa drugima parametrima. Mogućnosti sinteze su višestruke, a najadekvatnije su predstavljene vizelizacijom različitih vrsta digitalnih podatka, kao i mogućnošću iznalaženja i primene različitih vrsta modela. Može se zaključiti da sa rastućim potrebama geomorfologa, uspostavljanjem novih pitanja i hipoteza, računarsko- softverska analiza i modelovanje u geomorfologiji predstavljaju nezaobilazan pravac istraživanja.
