I'm working on geographical graphs and I would like to create graphs
where a variable is shown as RGB for a rectangle defined by logitude
and latitude. Over that graph I would like to show the world map for
the region. I have seen some examples at Visad source using
visad.jmet.GRIBCoordinateSystem. The question is if is there any
file with all the world map so I can select a region and put it over
my graph using this class?

 ftp://ftp.ssec.wisc.edu/pub/visad/OUTLSUPW

is a low-detail world map in a file format that VisAD
can read. I'm sure there are better world maps in
Shape files.
Yes, there are! I picked this up from another mailng list:

http://thuban.intevation.org/download.html#samples

In special: http://ftp.intevation.de/freegis/worlddata/freegis_worlddata-0.2.tar.gz

(18MB!)

I think they're all shapefiles.

Good luck,
Bill

Cheers,

Ugo
