Description

Added a flag (-c) to r.reclass.area.py to indicate that the input map is pre-clumped. This is useful for using r.reclass.area with clump maps generated from other tools such as r.clump4p (​http://sil.uc.edu/downloads.html#software) that can drastically reduce processing time.

Some issues have been pointed out in r.clump4p:

Would your patch work also with stock r.clump?

Yes, the flag just indicates the input map is already clumped so that it will skip the clumping phase of r.reclass.area. It doesn't matter which algorithm is used to do the clumping.

I have applied the patch in r59376.

Thanks closing the ticket.
