N2 - The purpose of this poster is to show a useful approach for determining the quality of forest growing stock (6SV) maps derived from ERS-1/2 tandem data. For the validation of the large-area maps, a special cross-comparison design based on freely available Earth Observation land cover (LC) products had to be developed due to unavailability of in situ measurements. A multiscale comparative assessment design, linking quality flags and LC products such as GlobCover, MODIS VCF, GLC2000 and AVHRR LC, has been applied. The sampling design, based on the FAO FRA2010 sampling design and the Degree Confluence Project, uses a 1 degree sampling grid with 10 × 10 km sample plots. The method provides appropriate information about plausibility and quality of the ERS forest GSV maps. Since similar global data sets will be available in the future (e.g. within the framework of ESA Sentinel programme), the developed approach is well suitable for scale and thematic independent accuracy assessment applications.
