I'm using GeodeticCalculator to calculate the
difference between the "x"s and "y"s. Unfortunately,
I'm not able to get it working. Any assistance would
be appreciated.
GeographicCRS geoCRS = DefaultGeographicCRS.WGS84;
DefaultEllipsoid e = (DefaultEllipsoid)
CRSUtilities.getHeadGeoEllipsoid(geoCRS);
GeodeticCalculator calc = new GeodeticCalculator(e);
Note 1: If you know that you want the WGS84 ellipsoid in all cases, you
can just use the default constructor:
GeodeticCalculator calc = new GeodeticCalculator();
Note 2: if you use one of latest Geotools snapshot (I'm not sure since
which milestone), you can write:
CoordinateReferenceSystem crs = DefaultGeographicCRS.WGS84;
GeodeticCalculator calc = new GeodeticCalculator(crs);
where 'crs' doesn't need to be geographic; GeodeticCalculator will
performs the needed transformations on the fly if you use
'setFooPosition' methods.
The code you sent seems correct. What are the coordinates values tested?
Martin.
