Re: [Matplotlib-users] Basemap interp nearest neighbor

2011-03-11 Thread Juan A. Saenz
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

Andrew, I sent this to you personally, unintentionally, and want it to be on the list too. So you have it doubled now, sorry. 2010/2/25 Andrew Charles : > 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 >
