An accuracy assessment of European Soil Sealing Dataset (SSL2009): Stara Miłosna area, Poland - a case study

The purpose of the undertaken survey is to assess the accuracy of the SSE2009, based on a reference dataset. The dataset contains 3,600 samples with the same spatial resolution as the final Soil Sealing Layer product and covers a rectangle of 36 km². The basis for assessing the accuracy was the photointerpretation of the orthophotomap. The overall accuracy with data division into 6 classes amounted to 65%; while divided into 2 classes: sealed and non-sealed reached 95%. The evaluation results accuracy may form the basis for future improvements in evaluation methods impervious surface.
