The IlvMapAreaRenderer and IlvMapCurveRenderer provide a geodetic
computation option. Geodetic computation includes date line
wrapping and reprojection of features that go outside of the
projection limits.
To create a renderer that performs geodetic computations, just pass
true
to the specified argument:
IlvShapeDataSource ds = new IlvShapeDataSource(shapeFile); ds.setManager(view.getManager()); // perform geodetic computations IlvMapAreaRenderer renderer = new IlvMapAreaRenderer(false, true); ds.setFeatureRenderer(renderer);
The figures show geodetic computation with
and without date line wrapping:
