Abstract

The extent of soil sealing or impervious surface area is one of the key indicators of environmental quality. In this study soil sealing assessment has focused on impervious surface coverage within land cover classes using very high resolution satellite data WorldView 2 and updated database of reference spatial data on national level -ZB GIS. The study area covers 40 km2 surrounding the town Trnava, Slovakia. It includes various land cover classes that provide a good test site for soil sealing assessment. Results of the soil sealing assessment provide useful inputs to planning and management activities at local scale.

Keywords: soil sealing, impervious surface area, land cover class, VHR satellite data
