I have developed a Java application (Latipics) that geotags pictures with location information pulled from Google Latitude. I use an open source library called Sanselan to read/write GPS coordinates from/into JPEGs' metadata.

It works mostly great except that Apple's Preview (stock JPEG viewer in OS X) seems to misinterpret the GPS longitude reference (see issue in more details).

Anyway, I'm considering dropping Sanselan but I can't find a suitable replacement (keep in mind I need to be able to write into the metadata, not just extract)

Thanks for the help.

  • Did you find a solution? I'm considering using Sanselan, but it looks like it hasn't had any updates in a while. Are you still using it? – Daniel Worthington Aug 06 '12 at 09:48
  • It's still implemented in an older version of my app that seems to work fine. It's been a while but I think I had to fix a bug (I forgot what it was but I could probably find it). I've since open-sourced my code at https://github.com/tbertran/Latipics – BlazingFrog Aug 06 '12 at 21:00

Look out for OpenGTS source code...you may get some lead for your needs!

There's nothing better than ExifTool. It's open source too and very reliable. It's not written in java, but there's nothing to stop you calling it from a java program.
