Comparison of the CORINE Land Cover data and Agricultural Land Use Monitoring Data as a basis for groundwater vulnerability mapping in the Peca border region Ra
In the article the land use data analysis as a basis for groundwater recharge area protection and vulnerability estimation in the region of Peca is represented. The area is positioned on the Karavanke mountains border region between Slovenia and Austria. Preliminary results of Slovene part are presented in the article. This paper wants to show usefulness of CORINE Land Cover (CLC) and major differences in results between CLC and more detailed data of Agricultural Land Use Monitoring (ALUM). Differences between results of both datasets are minor on first level of categorization especially when it comes to two most prevailing categories, but much bigger on next levels of more detailed nomenclature. Some categories are even not detected by CLC dataset. By both methodologies on first level of nomenclature forest is far prevailing land use category covering 78 (CLC) and 81 % (ALUM) of the area followed by agricultural land with about 16% (CLČ) and 17 % (ALUM). Differences important for groundwater vulnerability study occurred in artificial areas with 2 % (CLC) and 3,9 % (ALUM) surface.
