Re: Longitude, latitude maps

Hi all-

visad.jar does not support a native shapefile reader, so if
you use the shapefile, you will need to use something like

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?

is a low-detail world map in a file format that VisAD

Shape files.

I think they're all shapefiles.

Good luck,
