Hi all, is it possible to recode Nodata cells in a raster map?
How does r.thin handle Nodata value cells? In my case, it changes
Nodata value cells of the original raster (surrounding cells obtained
after the georeference operation of a scanned map) to the value 1.
Hence, I get a message error when I try to use r.to.vect command because
of these surrounding cells that have the value 1 instead of Nodata and
that constitute an area instead of a simple line.
thanks for any help....
