[GRASS-user] Reclass: Atributte a string

Greetings

I’m doing a reclass of rasters based on a rule file. In this file I’m doing a correspondence between values (1,2… 100) to other integer values.
Is it possible to do this but instead to done this to Numbers do this to Strings just like
1 = “Agriculture”
2,3,4= “Forest”

?
Thanks
Franz

You can associate category labels with each category using
r.categories. You can't "reclass" to a string.

Hello Glynn

Thanks for the reply. About using r.categories, can I apply it to a raster map and then export it as a “normal” raster?
Thanks
Franz

category labels are attached to an existing map; there's nothing to
export.

It might help if you explain what your ultimate goal is.
