Hi Wesley

I don't know about numpy
but here's an example in which a  gdal command for interpolating point .csv
values using inverse distance is called from python
the raster layer is created using vrt

*gdal_grid -a invdist:power=1.0:smoothing=50.0

*+str(ymin)+str(ymax)+" -of GTiff -ot Float64 -l input  input.vrt


you can reach other gdal_grid interpolation techniques here


i don't know if it these algorithms are still maintained
