[GRASS-user] External Database and projections

[Lorenzo Bottaccioli]

Hello everyone,

I not very expert in this field and searching on the web didn't clarify my
dubs.
I wanted to store a raster DEM and some vectors map in to an external DB,
GRASS will use the DEM in order to calculate various raster map of solar
radiation and need to store the again in the external DB. Than I'll use
r.mapcal to do some calculation of on the raster maps and i'll use the
vector map to extract this information. I don't need to store the
calculation I just need to perform the calculation and use the results
immediately.

My question is which could be a feasible solution for this? how do I manage
the fact that the input raster and vector map can have different
projection? What about if I want to define a default projection of the DB
and convert the maps when I load them in the DB?

The DB will probably be Postgis, do you have any other suggestion?

Thanks a lot

Lorenzo
