You could convert the raster layer to a vector layer. In the attribute
table you'll have a column with the raster value (the watershed values) and
the cat column, which gives you the unique identifier for each polygon.
Next you just convert the vector back to raster using the cat column as
raster v
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 f
I have a raster map with watersheds that are the same value. Is there
an easy way to reclass the map with every distinc basin to have a unique
value?
many thanks,
