You might have already thought of these techniques, but here are two options that quickly come to mind...
You should be be able to mask each watershed individually (from a vector layer), and then run r.reclass on the area within each watershed boundary. Alternatively, if you have a vector layer for watershed boundaries, what about creating a numeric attribute in which you assign each unique watershed a different number. Then, rasterize the watershed layer. If you have a lot of watersheds, it seems like the second option would be easier... and there obviously might be a more elegant solution that I'm not aware of. Hope that helps! Mike On Fri, Jul 5, 2013 at 2:03 PM, Stephen Sefick <[email protected]> wrote: > I have a raster map with watersheds that are the same value.
