could you describe the method? is it just an extraction of
category 2 from landcover_1m?

example on the r.li.mps help page]

I don't know if this matter but i use kubuntu natty. And
ask me for more info if necessary.
so forest1996 is my raster map of forest category (only).

r.li.mps --overwrite map=forest1996 conf=movwindow7 output=forest_p_mps7

Hi

could you describe the method? is it just an extraction of
category 2 from landcover_1m?

Not exactly, is an extraction of the category 5 (forest) from the landclass96 image

r.mapcalc ‘forest1996 = if (landclass96 == 5, 1, null())’

But the behaviour doesn’t change if you choose the category 5 of the landcover_1m

example on the r.li.mps help page]

It will be great…

Thank’s for reporting this as a bug
