I guess I need to look at the netcdf documents... and perhaps ask Nelson
a similar question. So: What are the standards we're using here? What's
the geodetic datums for horizontal and vertial employed here?
Nelson's question sounds a lot like the difference between Clarke 1866
and GRS80.

All,

NetcdfDatasetInfo info = dataSet.getInfo();
VariableEnhanced var =
(VariableEnhanced)dataSet.getVariables().get(0);
GridCoordSys grid = info.getGridCoordSys(var);
ProjectionImpl proj = grid.getProjection();
LatLonRect latlon = grid.getLatLonBoundingBox();
LatLonPointImpl point = latlon.getUpperRightPoint();
System.out.println(point.getLatitude());
System.out.println(point.getLongitude());
I have the above code, the issue is that the netcdf methods use a
pre-programmed (constant) radius for the earth, which is different than
the one that my data models use. As a result, the corner points are off
by a few hundredths of a degree (which translates to about 1.5km). Do
you know how I can force the projection to use a different radius?
