This study explores integrating land cover data with farm statistics to allocate dairy systems in Europe. Comparing CORINE land cover with national data for more accurate results reveals insights into agricultural landscapes.

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
