Conclusions • Land use statistics per farmtype are a very useful source as expert knowledge, however, • Land Use statistics are difficult to relate to CORINE land cover classes • CORINE land cover classes are informational at the landscape level but not at the field level Centre for Geo-Information
Conclusions • CORINE land cover classes are in fact very heterogeneous at the field level. • Surprisingly, the integration of CORINE with FSS-2 (Method 1) give similar results as the integration of National land cover and statistical data. Centre for Geo-Information
