Hello,
I have a raster with different categories (adjacent patches) but when I
buffer this raster file I get a buffer for the whole area and not for each
single patch.
I thought of a loop ( r.mapcalc "select patch cat x" - r.buffer x -
r.mapcalc " set buffer of patch x to null()" ) and then r.patch.
I already did some experiences with
COUNTER = 1
# while [ $COUNTER -lt $max ]; do
while [ $COUNTER < $max ]; do
echo The counter is $COUNTER
r.mapcalc "t1 = if(rast_in == $COUNTER,1,null())"
r.buffer input=t1 output=b.$COUNTER distance=500
let COUNTER=COUNTER+1
done
but failed because COUNTER was not recognized and I don't know at all, if
these bash statements work at all using GRASS.
I welcome any other idea.
Martin
