Hi all,
i want to simply divide my DEM into 30m grid cells - does
anyone know how to do this?
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 ?
i have previously used r.clump on a 30m DEM to create
unique spatial units.
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.
any help is very much appreciated!
thank you,
Janet
