Hi Ramiro,
We’ve discovered the problem is when the radius is set to less than the bin
size so passing in -b 10 (or any value over 2) your script runs fine.
The resolution in the XML file is the resolution used to calculate canopy /
non-canopy so if this is set to 1 and the bin size is set to 10, 100 cells
within each pixel will be used to calculate a canopy cover image with a 10 m
pixel size.
Hope this makes sense,
Dan
