I would like to create a raster map where the raster
catagory is equal to the attribute of the nearest site.
I'm not worried about the case where two sites are
an equal distance from the raster location since I
have a large uncertainty in my site locations anyway.The only approach I have come up with is to modify
the code for s.surf.idw so that rather than computing
a weighted average, the new code would simply use
the attribute of the nearest neighbor. Though this
would not be too difficult, is the facility already
available (and I can't find it).
Just set npoints=1 and you will get the value of the nearest neighbor.
