Re: [idvusers] reading model grids from nc files

Hi Stuart....

If the GeoGrid is "ucar.nc2.dataset.grid.GeoGrid", then there is a
method, getCoordinateSystem() which returns a "GridCoordSys" object.
There are methods in there for getting a lat/lon bounding box, and


Hope that's what you are looking for....??
