reclassification

Hi all,

I have some problems trying to reclassify some Arc/Info original data. I
have the following:

- 10 vegetation types (4, 6, 10, 15, 27, 33, 34, 41, 42, 50)
- 11827 areas

The areas are classified as categories and the veg types are classified as
descriptions.

I want to reclassify the map in function of the veg types instead of areas,
but running r.reclass non-interactively I can't accomplish this. And with
the interactive mode is a little crazy (11827!).

Some ideas?

Thanks a lot

  This looks like an ideal situation for keeping attribute information in
postgreSQL. Making changes in attribute data (perhaps in a copy of the
original table) would be quite easy with sql statements.

Try r.gdbase:

r.gdbase input=in output=out database=db rules=rec analysis=reclass

you must create dbase file 'MAPSET/dbase/db'(text) and reclass file 'rec' first

(easy)
