Sažetak
The purpose of this research was to determine the methodology of land capability evaluation with regard to an array of objective limiting factors when growing, for example, perennial crops. The methodology of relief parameterization was used in the method for calculating geomorphological parameters, and pedometric mapping methods were used to calculate pedological variables. Inventory of the actual condition of land cover was made based on sketches and maps that were gathered during field research. These sketches were then geo-referenced and overlapped with LANDSAT satellite images to determine the actual situation. The best locations for a particular type of perennial plantation were selected by using logic and spatial queries. Best locations (in this example for vineyards) were identified as an area overlap (areas with, according to the spatial plan, either valuable, especially valuable or other arable soils, southern relief exposition with the total annual incident light >1, 208 KWh/m2, and the location where the relief slope is not higher than 12% and lower than 2%, or where elevation exceeds 110 m and soil acidity does not exceed 5.6 pH). The query resulted in a simple map. The map shows areas which are either suitable for viticulture (1) or not suitable for viticulture (0). Similar approach could be used also for thematic maps of different purposes, for example, urbanization maps, or mapping valuable sources of water, gas, thermal wells and other resources of special importance for the country. According to the results obtained in our example of finding the methodology for development of thematic maps in GIS environment, the total of 17, 782 ha in the County area is suitable for viticulture. The best way of developing spatial plans for particular crops would be to develop maps of negative scores for all crops, and then to standardize these values to find the best possible crop for each location. Thematic GIS layers can be used as the foundation for loans, advice on what crop to choose, making decisions on land re- allocation and land use, reconstruction i.e. modified land use.
