Hello all,<br><br>I'm writing a script to autodetect the null space bordering a raster while ignoring interior voids. I expand the region to slightly larger than the data area, reclass nulls as 1, and then run r.clump to get discrete groups. <br>
<br>My question is, does r.clump process nulls in any particular order? >From what I'm seeing, my border null area always ends up being the highest numbered in r.clump. Since I need to detect which null clump represents the border, this would be very convenient. <br>
<br>Any insight?<br><br>Jamie<br><br><br>
