[GRASS-user] obtaining raster map from point values

[Alberto Pettazzi]

Hi Everybody!

I am trying to obtain a raster map of precipitation derived from MSG 
satellite. I imported in GRASS from a txt file containing 
lon-lat-precipitation values.

I used

r.in.xyz

and what I obtained is the jpeg file attached. As you can see, only a 
series of dots is represented, corresponding to the 
lon-lat-precipitation values contained in the file. what can I do in 
order to convert the dots in something that looks more like a "cloud"?

I also tried

v.in.ascii + v.to.rast, but the result was almost identical.

Thank you,
