x,y=map(*N.meshgrid(LON,LAT)) you can leave the other statements in. If you still have memory issues, bring the readshapefile call out, and draw the shapes whose coordinates are stored in the instance variable map.DSE_REGIONS manually in the loop. -Jeff On Fri, Oct 14, 2011 at 10:

Re: [Matplotlib-users] Basemap interp nearest neighbor

basemap interp function is just a convenience function for simple regridding (linear, cubic and nearest neighbor). scipy.interpolate (http://docs.scipy.org/doc/scipy/reference/interpolate.html) provides many more options. -Jeff On Mon, Mar 7, 2011 at 8:23 AM, Jeff Whitaker <mailto:
