Processing Land cover Data


I am working on my Master thesis and need to process the Land cover Data for defined areas. I wrote a short Python script to process the .nc file but no matter what coordinates i enter the lccs_class variable is always 210 (water) and the processed flag and observation count variables are 0 respectively.

I have tried this with data from different years and the outcome is always the same.

Are there any known problems processing the land cover files, or am i doing something wrong?
