There are suggestions in literature about which data layers are the most appropriate for landscape classification at a specific scale (regional, national, continental). In the research an objective numerical method is presented which can help us to select layers before using them in the classification process at a chosen scale. The main part of the method deals with computation of coefficient of variance for different spatial units (with different areas). For this purpose Zonal Statistics and other tools were used. Also a python script has been written which includes Arcpy, Numpy and Pycluster tools. With our method different groups of layers were identified: layers that are more appropriate for small scale classification, layers that are more appropriate for large scale classification and layers that can act as to noisy for landscape classification at any scale. Our study area was the Republic of Slovenia. More than 30 data layers have been tested.

The proposed European Union indicators for defining areas less suitable for agriculture in Slovenia are not entirely appropriate because taking them into account would omit some distinctly and clearly unsuitable areas–for example, Suha krajina (Dry Carniola) and Bela krajina (White Carniola)–and farmers would be unjustifiably financially harmed. In such a case, every European Union member state has the right to propose an additional indicator to reduce such discrepancies. With regard to actual natural conditions, in Slovenia especially some karst landscapes would be unjustifiably omitted, and so we have proposed a karst indicator as an additional criterion based on the distribution of karst (i.e., carbonate) rocks. Through spatial coverage of karst rocks and soils, we determined whether more reasonable and less strict application of European criteria regarding soil could be satisfactory for better results in defining areas less suitable for agriculture in Slovenia.

The eleventh monograph GIS in Slovenia contains 27 scientific and professional chapters. The most interesting chapters were presented at the symposium of the same name, which was organized in the autumn 2012.
