[GRASS-user] Using r.reclass.area with an NDVI map

[António Rocha]

Greetings
I have an NDVI map but it's not continuous: i mean, I have a few patches 
with values and areas in my raster map without values.
I want to apply r.reclass.area in order to eliminate patches with less 
than 2ha. My question is:
shall I convert NDVI pixels to 1 (creating a mask of valid pixels) or 
can I just use as it is (with values ranging from -1 to 1)? Because if 
r.reclass.area uses r.clump 2 pixels with different NDVI values are not 
"categorized toghetter. Right?
THanks
Antonio
