Analiza promena kapaciteta kopa 'Garajevac - Istok' primenom GIS tehnologije

Abstract

The paper discusses the concept of construction and monitoring of capacity changes - the volume of the "Garajevac-Istok" excavation (mine), located in the cadastral municipality of Novi Bečej. Namely, in the earlier period, the physical surface of the Earth and geospace in general were shown two-dimensionally (2D), in a plane, by some of the cartographic methods (contour lines, points heights, hypsometry) or three-dimensionally (3D), by modeling of reliefs and relief cards. The cartographic principles of terrain making and visualizing on relief mapping models allow the creation of 3D views, but not enough quality and engineering precise 3D terrain models. In addition, there is a possibility of quantitative and qualitative assessment of the terrain on the mentioned models not to be accurate enough. With new technologies, the 3D geospatial display mode changes, and the concept of digital terrain modeling (DTM) is being applied. The main goal of the work is to create 3D models and to give an analysis of the "Garajevac-Istok" mine for a certain period of exploitation

U radu se razmatra koncept izrade i praćenja promena kapaciteta - kubature kopa 'Garajevac - istok', koji se nalazi na katastarskoj opštini Novi Bečej. Ranije su se fizička površ Zemlje i geoprostor uopšte prikazivali dvodimenzionalno (2D) u ravni, nekom od kartografskih metoda (izolinije, kote, hipsoskala) ili trodimenzionalno (3D), izradom maketa i reljefnih karata. Kartografski principi izrade i vizualizacije terena na reljefnim kartografskim modelima omogućuju stvaranje 3D prikaza, ali ne i dovoljno kvalitetnog i inženjerski preciznog 3D modela terena. Pritom je mogućnost kvantitativne i kvalitativne ocene terena na pomenutim modelima otežan i nije dovoljno tačan. Sa pojavom novih tehnologija menja se način 3D prikaza geoprostora, odnosno primenjuje se koncept izrade digitalnih modela terena (DMT). Osnovni cilj rada jeste kreiranje 3D modela i uporedna analiza kubature kopa 'Garajevac - istok' za određeni period eksploatacije.
