>                 Key: SIS-347
>                 URL: https://issues.apache.org/jira/browse/SIS-347
>             Project: Spatial Information Systems
>          Issue Type: Bug
>          Components: Metadata
>    Affects Versions: 0.4, 0.5, 0.6, 0.7
>            Reporter: Martin Desruisseaux
>            Assignee: Martin Desruisseaux
>             Fix For: 0.8
>
>
> Steps to reproduce:
> {code:java}
> DefaultGeographicBoundingBox box = new DefaultGeographicBoundingBox();
> box.setBounds(-180, +180, -90, 90);
> System.out.println(Extents.area(box));
> {code}
> The above computes zero with SIS 0.7. The reason is in the line that take in account boxes crossing the anti-meridian; the span reduction performed there is a little bit too much aggressive.
