[Qgis-user] Spatial resampling of a point vector layer using QGIS

[Nicolas Cadieux]

Hi Giacomo.

You can access gdal_grid from qgis. (Raster menu).  Use the moving average algorithm. 
 If it's not there, you may need to modify the gdal command line by pressing the yellow pencil.

> I have a vector layer with points located on a regular square grid of 2Km. The layer has a column with a numeric value (crop yield) for each point.

> I would like to resample the vector to a grid of 1Km, and the new points should have the crop yield value represented by the average of the 4 points surrounding.
