[GRASS-user] Plotting estimation.-

Dear list,

I have a situation and I hope you can help me.

I have a kriging-like estimation from an area (a matrix with coordinates and the kriging estimation value) and a vector map and I would like put this estimation inside it.

I have used v.to.rast but the returned map has a very poor resolution (it doesn’t follow the real borders, for example, but big squares; I suppose, of course, I’m doing something wrong).

You can see the map here: https://sites.google.com/site/freddyvate01/vector2raster.png?attredirects=0 .

Cheers.

Thanks Maris.

Can you be a little more specific, please?

I read on v.to.rast: “Before running v.to.rast, the user should therefore ensure that the current geographic region is correctly set and that the region resolution is at the desired level” but how do I know to set correctly the geographic region?

Thanks.

Hi Freddy, try:

g.region vect=VectorMapThatYouWantToTurnToRast
g.region res=VerySmallNumber
v.to.rast

Best,
Nick
