ABSTRACT
European Copernicus (former GMES) GIO Pan-EU Land Monitoring service is to provide land cover information to users in the field of environmental and other terrestrial applications. The GIO Land Monitoring service includes CORINE LC inventories and the 5 high resolution layers (HRLs) that characterized 5 main land cover types: impervious areas, forest, permanent grasslands, wetlands, and water bodies - for the reference year 2012. The HRLs are generated using automated image classification by external service providers [2]. This presentation is focused on the analysis of the two HRLs: impervious areas and tree cover layer. We have performed the verification of both HRLs against the available national in-situ data. The preliminary results of the accuracy assessment showed overall relatively good agreement between the provided HRLs and in-situ data. The disagreement was identified over the scattered settlements, patches of mature orchards or mountains forest. The HRLs can be a valuable, additional source of up-to-date information on land cover status.
