surface gerenation

----- Begin Included Message -----

Hello Grass users,

I have a file with precipitation values (a sites file) and I would like to
generate a surface map from these precipitation values, so that I can create
the precipitation isolines.

Any suggestions?

Thanks.

Cristina you can first use one of the programs like s.surf.tps or s.surf.idw to create a raster file of the area. If you use r.contour in addition of that you can create a vector file with the isolines
