I need to produce some plots from netcdf files.  The data is gridded
(longitude and lattitude).  In this particular situation I do not need land
masses masked (my lon/lat grid is over the open ocean), but I would like to
do that in the future.  Specifically, I am trying to show average sea
surface temperature over a region of open ocean.  I checked GNUplot's sample
plots and didn't see any that looked like what I am used to seeing in
published articles.  I'm relatively new to Octave still, so bear with me.
My questions are:

1) Can Octave (GNUplot) produce nice plots of data in a lon/lat grid?
2) If so, how can I do it or where can I look for instruction/resources?
Octave Manual didn't help, or I didn't see the clues...
3) Also, how would I overlay land masses if needed?

I have the octcdf package installed and can already pull the data from my
netcdf files.

Thanks for your help!

If you can't get octave to work for you, there is a very good open source 
package called
GMT. It is specifically designed for making maps. Here is the link:
