ISO 19115 (metadata) defines "GeographicBoundingBox", which may be seen=20
as a kind of envelope with the CRS fixed to WGS 84 (EPSG:4326). Geotools=20
provides an implementation with convenience transformation method:

raphicBoundingBoxImpl.html


This implementation has a GeographicBoundingBoxImpl(Envelope)=20
constructor, which expect an arbitrary ISO 19107 envelope and transform=20
it to WGS 84 as needed.

Note: if you need to work with JTS envelope instead of ISO 19107 ones,=20
then you may consider ReferencedEnvelope, which is both a JTS envelope=20
and an ISO 19107 implementation.
