I have a little question about the natural neighbor
interpolation/extrapolation code/package found in the natgrid part of
ngmath.
The question is: Is it possible to use the extrapolation mode while telling
it (the natural neighbor interpolation code) that for all extrapolated point
which are beyond a certain range (say 50 meters) of the convex hul (the
polygon created by the data I'm using as input for the natural neighbor
operation), no extrapolation should be done, the default "no data" value
should be used for those points?
All that is because I'm working on a project where I need extrapolation but
I don't want to have it too far from the data I have and it would be simpler
for me if there was a way to do this in the code instead of having to code
something myself.
Thanks!
Patrick Laberge
