C.A. Mücher, Centre for Geo-Information 22 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
C.A. Mücher, Centre for Geo-Information 23 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.
