I’ve written a script – gpx2ipod – to enable Mac-based paperless geocaching with an iPod.
Mac-based paperless caching for people who own an iPod but not a PDA. Batch-converts a pile of .gpx files to plain text for use with the iPod’s “Notes” feature. Super-fast — cut your geocaching prep time to a few minutes. gpx2ipod handles both individual and Pocket Query (multiple-cache).gpx files. Cache files will display alphabetically on the iPod for easy access in the field. gpx2ipod can inject generated text files directly into your iPod (most users) or into a local “output” folder (you might not have an iPod but might still want the text files for other purposes). gpx2ipod is a Terminal application (shell script), but can be run painlessly with a double-click — no shell experience required.
The script requires gpsbabel 1.3.4 or higher, and can be downloaded either with or without gpsbabel bundled.
For me, it’s been a very fast way to reduce prep time before going caching – I can now build and receive a pocket query from geocaching.com, then load hundreds of waypoints into the GPSr and all of their metadata into the iPod in a few minutes (previously I had to selectively print out data pages for each cache I intended to visit – a laborious and wasteful process).
Just received an email from a super-happy beta tester who’s as excited by this as I am – gratifying to know I’m not just barking up my own tree. A future version will feed gpx files to the GPSr and text files to the iPod in the same run.
This tool is also available through VersionTracker.

Once upon a time, the “Paper or plastic?” question seemed like it could go either way. Choose plastic and you’re choosing something that may be stuck in landfills for hundreds of years. Choose paper and you’re sacrificing trees (“it takes 14 million trees to produce the 10 billion paper grocery bags used every year by Americans”). But it’s way more complicated than that. From an
