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
Unidata's ShapefileAdapter (part of the IDV package).

Also, for an example of maps in a display with lat/lon
axis labels, see the code at:

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.
Yes, there are! I picked this up from another mailng list:

I think they're all shapefiles.

Good luck,
