Abstract:
As Geographic Information System (GIS), as part of the Geoinformation Sciences, deals with a complete system of creating, handling, storing, manipulating, using analysis and presenting information related to the Earth’s surface it is in the direct function of solving fundamental problems / issues arising from that process. The organization of data is according to the system of thematic data layers. The research conducted includes the formation of GIS for different types of research for the Tara Mountain area, Serbia. During these researches, various thematic data layers were created. The types of data used in the creation of these layers are: vector, attribute with organized database, raster data and digital models. The processed contents present abiotic, biotic and anthropogenic elements of the real environment. The paper presents specific indicators created in the process of GIS development. Qualitative, quantitative and visual representation of the real environment was achieved. The results of multicriteria thematic and topological analyzes are also presented. System decisioning support is achieved.
