methods	Grid Data Set: the derivation was carried out by the service union of the Federal Statistical Office of Switzerland (GEOSTAT) 1) The 100 x 100m grid of SLUS was reclassified according to the 15 given classes of CLC, level 2. 2) Conversion of grid to polygons (GRIDPOLY) 3) ELIMINATE of provisional Class 60 to neighbouring patches with the longest common boundary 4) Reconversion to grid format with cell size 50x50 m 5) Generalisation with BLOCKMAJORITY in 5x5 blocks and resampling into 250x250m. 6) Iterative filling of zero values with FOCALMAJORITY functions in 7x7 and extended 9x9 blocks, circles (3 cells) and 3x3 blocks. MERGE with 250m grid in point 5) above. 7) In the end one cell was left that was corrected manually (hahaha).
