Re: Higher resolution topographic gempak sat files

Alan,

I have created both 30 second and 5 minute global topography (dem) data
sets.
The 5 minute dem data has bathymetry, while the 30 second data set does
not.

I provide these as a grid
(http://www.unidata.ucar.edu/downloads/gempak/tables/)
for use with a program I call GDTOPO which allows users to create a
subset for a Gempak grid file. However, it would be possible to map the
grid into an image to use as a background using the same grid to image
conversion that I do for our
radar composite images.

If you can provide some information regarding the resolution
(pixel-->km) you
need, I can look into making some background images.
