Hi Jeff,
Sorry, an XYZ file is simply an ASCII file which can have either
LON,LAT,HEIGHT entries or Cartesian X,Y,HEIGHT entries. I think I have
confused myself a little here, as all I need to do is print the
LON,LAT,HEIGHT data to a file and I've finished, and basemap is not
required for this. The original question was whether once a basemap
had been defined is there an easy way to extract the Cartesian
coordinates to produce an XYZ file containing the Cartesian
coordinates for the chosen projection rather than the geographic ones?
Thanks
Mat
PS. This is in all in the context of converting data for use in a
software package called MIKE. It sadly lacks the ability to deal with
NetCDF files directly.
Mat: If you have the longitudes and latitudes in numpy arrays lons,
lats, and m is a Basemap instance,
x,y = m(lons,lats)
gives you the projection coordinates.

Hi,
I was wondering how hard it would be to generate xyz format files
from netcdf files using python-netcdf4 and basemap? It seems that
basemap has the capabilities to do those sort of conversions, but I
am a bit of a novice to map data and I'm not sure what would be the
correct approach to this.
Many Thanks
Mat
