Validation of Copernicus High Resolution Layer on Imperviousness degree for 2006, 2009 and 2012

Pan-European High Resolution Layers (HRL) provide information on specific land cover characteristics, and are complementary to land cover / land use mapping such as in the CORINE land cover (CLC) datasets as part of the Land Monitoring Service (land.copernicus.eu) of the Copernicus programme, managed by the EC. The HRLs are produced from 20 m resolution satellite imagery through a combination of automatic processing and interactive rule-based classification. 5 themes have been identified so far, corresponding with the main themes from CLC, i.e. imperviousness, (the level of sealed soil), tree cover density and forest type, permanent grasslands, wetlands and water bodies. Pixels of 20 by 20 m are aggregated into 100 by 100 m grid cells for final products. The imperviousness layer was the first to be produced during 2006-2008 from multi-sensor, bi-temporal and ortho-rectified satellite imagery, the same as used for the CORINE Land Cover 2006 update. The production of IMD2006 covered 38 European countries (32 EEA Member States and 6 West-Balkan countries). Since the 2006 production, a time series of imperviousness has been produced for reference years 2009 and recently 2012 over the whole area covered by the 39 member and cooperating countries of the European Environment Agency (EEA) representing a total of 6 million km². For each year it is available as a raster layer with 20 m resolution. At the time of undertaking this study, the area delivered for the year 2012 was around 90% of the total area and the study is based on this area
