You are going to have to be more specific. Are you trying to
interpolate a rainfall map from several pluviometric stations or do
you have precipitation maps from some other source and want to open
them in Grass?

To interpolate the rainfall check out the v.surf.* modules

You then need to import the data in Grass. After you created the
correct location and mapset you can use r.in.gdal to import the data.

If your .tiff image has projection information you can use it to
create the location

Hi

I've got TRMM "rainfall" data (in .tiff format), I want to do analysis on
the data and estimate how much rainfall has fallen to the surface, check if
there is possibility for flooding to occur. Which commands to pass to
perform this?

Thanks, the publications were great!

In the same context, I would like to ask for very simple tips about
how to import several rainfall gauge stations.

For instance, a csv or txt file with the following columns "gauge
station name", owner, North, East, "annual rainfall, Elevation, "max
24 hrs".

I have failed from the db.connection or db.in.org (if that is the
begining) and the availa

Then, it would be nice to link a data serie (date, rain) with its gauge station.

Any tips to make it easer will be very welcome,
