Jon-The grib data represent a disc of the earth so the corners are off the earth, thus the NaN's. Even so, the VerticalPerspectiveView does not presently support a non-spherical earth, so the data are not exactly navigated. This is a known issue and one that we have not yet had the time to address.

Hi, We have a GRIB file can mostly be read using NetCDF-Java, except that the GridCoordSystem's lat-lon bounding box is a set of four NaNs. It uses a VerticalPerspectiveView projection. The attached test file may help to diagnose the problem and produces the following output: class ucar.unidata.geoloc.projection.VerticalPerspectiveView ll: NaNS NaNW+ ur: NaNS NaNW The data file itself can be downloaded from http://dl.dropbox.com/u/2984763/MSG2-SEVI-MSGCLMK-0100-0100-20091028120000.000000000Z-958792.grb. Can anyone offer any pointers? Is there a bug in the VerticalPerspectiveView code? Thanks, Jon ------------------------------------------------------------------------ _______________________________________________ netcdf-java mailing list netcdf-java@xxxxxxxxxxxxxxxxFor list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/
