[GRASSLIST:1421] PostGis & GRASS

GRASS GRASS user
,
1

Dear users,
I'm starting develooping one application in wich i
would like to use:

- PostGis as a database to retrive real-time
climatic data
- R as statistical software for validate and
complete missing data
- Grass as model environmenteal to elaborate data
- Mapserver as web viewer

In order to combine such environments I wuold have
some question:

- Is it possible linke R with PostGIS in the same
way I link R with PostgreSQL?
- I'd like to use a stable version of GRASS but
GRASS 5.1 is very attractive, so how much instable
it is?

Also, if anyone has try to make something like
this or has some suggestions it would be very
appreciated.....

Thanks you all

Do you mean PostGIS (for vector geometry) or PostgreSQL (for
data sets)?

- R as statistical software for validate and
complete missing data
- Grass as model environmenteal to elaborate data
- Mapserver as web viewer

You can link R to PostgreSQL:

You can link R to GDAL:

- I'd like to use a stable version of GRASS but

Good question :slight_smile: We use it already but things can change
without being advertised.

Also, if anyone has try to make something like
this or has some suggestions it would be very
appreciated.....

Thanks you all
