It's not clear to me what result you want. What's the resolution of
your DEM? Do you need to change the resolution? or create a vector
grid ?<br>

<div>i have previously used r.clump on a 30m DEM to create
unique spatial units.</div>
<div>however, since r.clump finds all areas of contiguous cell
category values and groups them to form physically discrete
areas, i end up with some spatial areas that may be larger
than 30m.</div>
<div>any help is very much appreciated!</div>
<div>thank you,</div>
