Unfortunately, no, at the moment JTS does not provide any special
handling for geodetic data. Hopefully this will be added in a future
release.
You might look at PostGIS - it has a Geography type [1] which provides a
lot of geodetic functionality. And PostgreSQL is a better DB as well!

Hello there,
I'm a non-professional programmer who has developed some fairly
extensive applications in PHP and MySQL. MySQL have been slow to
develop their geometry functions so I am just starting to use Albert
Rovira's msudf library of user-defined geometry functions which uses
GEOS which of course uses your JTS.
MySQL's native functions are not / not all 180-degree friendly ie
anti-meridian friendly so I have had to split lines and polygons which
cross the 180 degree meridian before processing them as I wish to.
Can you please tell me whether JTS handles the 180 degree meridian
"properly" ? At this stage I don't think that I *need* it to (because
I have split geometries up) but it might be a bonus (eg processing
speed) if it did do so. I have tried to find reference to this in
documentation; sorry if I have overlooked anything obvious.
Many thanks.
Best regards,
Mike McCutcheon
