Idea Wrapup: Java Geotagging

Being the proud owner of a GPS Logger I though a bit about developing a Java applications for geotagging photos and analyzing my tracks (e.g. for running, biking and hiking). While this is all possible with online applications (e.g. barrique) I searched a lot for free offline tools. I did find some applications, which provide sufficient functionality (e.g. GeoSetter, which works really fine) but only work on Windows

Unfortunately I currently have not enough time sit down and code a fine app, but I did some search and found out that it might be rather easy to mash up such tool. First thing is parsing of GPS data -> That’s just XML (with GPX) and should be rather easy. Reading time from the photos EXIF tags can be done with Drew Noakes library. It also allows reading of the EXIF thumbnails for boosting “time to display”. The visualization can be done with the Swing-X WS JXMapViewer component (hopefully). Writing the geo tags using EXIF might be done with Imagero (Java, a bit on the expensive side) or ExifTool (Perl, open source). I’d appreciate feedback on possible other libs
