Jeff, thanks for your reply.
One situation where one might require masked nearest neighbor
interpolation is when, on a given fixed grid, interpolating velocities
on cell corners (B-grid) to faces (C-grid). Cells will be defined as
either land or ocean cells, masked or un-masked respectively. Th
If I think of something, I'll let you know.
In the meantime, I'd like to point out the following:
Nearest neighbor returns a masked interpolation point if the nearest
neighbor is masked (this is just what you've already told me). If there
are two equidistant neighbors, it returns the one on the

For convenience, I recently heard about numpy.meshgrid, which does the
job for you. See its __doc__, but it's fairly

Andrew, I sent this to you personally, unintentionally, and want it to
be on the list too. So you have it doubled now, sorry.

I'm trying to interpolate from one grid to another using Basemap's
interp function. It seems to want the lat and lon axis of the new grid
to have the same shape:
3524 if xout.shape != yout.shape:
3535 raise ValueError, 'xout and yout must have same shape!'
The grid I'm interpolating to is 14
11 matches
