Re: [Qgis-user] Gridding vector data

[Nicolas Cadieux]

Hi,

There is the terrain modelling tools in Qgis.  You can try inverse distance 
weight.  You also have tool the gdal_grid tools in the raster menu and in 
processing. Keep in mind that you can modify the option to get interpolation 
methods that are not in the GUI.  

I think Grass has a local or universal Krigging also.  If not. You could find 
that in CrimeStat I think.

I normally grid data outside of QGIS using GMT and then import surfer
grids (or Ascii raster) into QGIS. Not really tried the gridding
options within QGIS

[Qgis-user] Gridding vector data

[Grant Boxer]

I am trying to find a good option for gridding geochemical soil sampling
data. I have tried the raster>analyse>Grid option, plus a couple of others
in the SAGA toolbox, but I have found it difficult to get a good smooth
result. Does anyone have any other suggestions?
