POLDER global clumping index map
version 2009/03
contact: jan.pisek@utoronto, chenj@geog.utoronto.ca

-data format: 8 bit unsigned (the pix file is georeferenced)
-Values are scaled by 100, i.e.  value 66 -> omega=0.66
-if no data from POLDER 3 were available, results from POLDER 1 were used
-if there were no results from POLDER 3 nor POLDER 1, mean values for dominant
land cover type from GLC200 classification within POLDER pixel were used

1-100 - range of clumping index values (don't forget to scale by 100)
253 - non-vegetated areas
254 - water
