I don't think axis order can be the reason as it only works if i use both:
- Hints.putSystemDefault(Hints.FORCE_LONGITUDE_FIRST_AXIS_ORDER,
Boolean.TRUE);
-
mapcontent.getViewport().setCoordinateReferenceSystem(CRS.decode("EPSG:4326"));
So the axis order should be set the same for both, no?
But there is definitely a difference between the two definitions as
CRS.decode("EPSG:4326") gives me:
GEOGCS["WGS 84",
DATUM["World Geodetic System 1984",
SPHEROID["WGS 84", 6378137.0, 298.257223563, AUTHORITY["EPSG","7030"]],
AUTHORITY["EPSG","6326"]],
PRIMEM["Greenwich", 0.0, AUTHORITY["EPSG","8901"]],
UNIT["degree", 0.017453292519943295],
AXIS["Geodetic longitude", EAST],
AXIS["Geodetic latitude", NORTH],
AUTHORITY["EPSG","4326"]]
and DefaultGeographicCRS.WGS84 results in:
GEOGCS["WGS84(DD)",
DATUM["WGS84",
SPHEROID["WGS84", 6378137.0, 298.257223563]],
PRIMEM["Greenwich", 0.0],
UNIT["degree", 0.017453292519943295],
AXIS["Geodetic longitude", EAST],
AXIS["Geodetic latitude", NORTH]]
