Hi John,
Just to return to this problem with some more info. The following program:
public static void main(String[] args) throws Exception {
NetcdfDataset nc =
NetcdfDataset.openDataset("http://topaz.nersc.no/thredds/dodsC/topaz/mersea-ipv2/arctic/tmipv2a-class1-b-be";);
GridDataset gd = (GridDataset)TypedDatasetFactory.open(FeatureType.GRID,
nc, null, null);
GridDatatype tmp = gd.findGridDatatype("temperature");
GridCoordSystem coordSys = tmp.getCoordinateSystem();
System.out.println("X axis type: " +
coordSys.getXHorizAxis().getAxisType());
System.out.println("Y axis type: " +
coordSys.getYHorizAxis().getAxisType());
System.out.println("Z axis type: " +
coordSys.getVerticalAxis().getAxisType());
System.out.println("T axis type: " +
coordSys.getTimeAxis().getAxisType());
nc.close();
}
prints out:
X axis type: null
Y axis type: GeoY
Z axis type: Height
T axis type: Time
The variable in question is on a polar stereographic grid. The types
of the Y, Z and T axes are correctly recognized as the above output
shows. I can't figure out why the X axis is not. This problem has
only recently appeared, and it might have occurred due to a change in
the version of nj4 that we use (or the OPeNDAP provider might have
changed something).
Can you shed any light on this?
Thanks, Jon
