[gradsusr] plot Cross section of topography

[Martin V. Mathew]

Hi

I have prepared a program 'bathymap.gs' to plot shaded cross section of
topography data (Please see the attached figure).
This program uses netcdf file of ETOPO 5-minute resolution gridded
elevation data for topography.
A description of the program and other relevant details are given as
comment text in the beginning of the program.


Hope this will help you

Regards
Martin
