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. .

Highlights

The elevation of the terrain in the cartographic sense can be represented by contours lines, shadows, hypsometry or their combination
digital terrain modeling (DTM) is the mathematical representation of the continuous terrain surface based on a representative set of data in the form of points, lines and other characteristic details collected on the ground (Li et al, 2005)
The subject of this paper is the geomorphological changes in the terrain and the capacity of the "Garajevac - Istok" surface mine in the cadastral municipality of Novi Bečej in the period of 2015, and a comparison with the situation from the period of 2014 and 2013

Summary

Introduction

The elevation of the terrain (relief) in the cartographic sense can be represented by contours lines, shadows, hypsometry or their combination. DTM is the mathematical (statistical) representation of the continuous terrain surface based on a representative set of data in the form of points, lines and other characteristic details collected on the ground (Li et al, 2005). The surface of the terrain in a digital form can be presented in three ways (Figure 1): contour lines; the function of the two variables; and volumetric (volume) model. The comparison of the condition of the terrain from 2015 is shown by the curve of the capacity (volume) in relation to the physical - topographic surface and the creation of profiles for the purpose of future use of data in the analysis and maintenance of the land using DTM. For DTM in the form of Grid (Figure 2 under b), the volume V4 can be determined according to the formula: V4. Based on these two formulas, the volume V of the excavation and the embankment, and based on the DTM engineering design can be expressed:
