The research determines the methods for site estimation taking into account a number of objective limiting factors that occur in grapevine growing. The relief parameterization was used for calculation of geomorphological parameters. The pedometric mapping was used for calculation of pedological variables. The actual condition of land cover was registered by sketches and plans gathered during on-site investigations. Afterwards the sketches were georeferenced and over-lapped to LANDSAT satellite images in order to verify the actual situation. Logical spatial inquieries were used in the selection of optimal sites for a particular kind of permanent plantations. The optimal vineyard site was defined as an overlapping of locations where, based on the physical plan you can find either valuable or especially valuable land, or other arable land and of southern relief exposition with a total of an annual incoming light level above 1208 KWh/m2 as well as the relief sloping not above 12% and under 2%.
This implies an altitude not lower than 110 m and the soil acidity up to 5.6 pH. The inquiery produced a simple map showing the areas which are either suitable (1) or not (0) for grapevine growing.
Estimation showed that a total of 17 782 ha of the County are suitable for grapevine growing. Compared to the actual situation (1612 ha) it is discernible that about 10% of available resources have been used.
