[GRASS-user] strange behaviour of v.surf.idw

Hello everyone. In these days I was using IDW to make an easy interpolation of a point features layer, and I faced a strange behaviour. My dataset is composed of 122 points, and the attribute to be interpolated is Z, in the sample I attach. I've interploated first in a narrow region around a peak.

Re: [GRASS-user] Interpolation with faultlines?

It's the same question I was going to ask. It would be an important advance in Grass, as I'm obliged to use commercial sw to do it (Esri) both to interpolate with barriers and to do 3D TINs with constraints. Giovanni 2008/2/13, Carlos Guâno Grohmann <[EMAIL PROTECTED]>: > I remember that some tim

Re: [GRASS-user] Installing R under cygwin

Hi Jan, Why do you want R under Cygwin? You simply need R to be installed under Windows. Cygwin shell "talks" with R windows version. - So, first install R under Windows. - Run Cygwin, run grass. It will open an XWindow, but don't use it. Go back to your cygwin window and run R. It will invoke

[GRASS-user] wxpython gui: error while loding avevry first layer

Hi, I'm playing with the new gui. I've tried it yesterday for the first time: it rocks! There are some warning and little errors the come raised with some tasks, but everything seems to work fine. The first error I've experimented is: 23:57:44: Can not enumerate files in directory '/home/giova/.kd
