Version 1.3 of my “geocaching with an ipod” system gpx2ipod is now available, with an all-new interface for establishing text encoding / international character sets. So all you Swedish and Russian and Chinese cachers should now see your native language rendered with all the proper characters on your iPods!

This update based in part on GPL’d contributions from a volunteer Swedish developer. This kind of collaboration is what open source is all about – on my own, I may never have gotten around to looking into the ins and outs of dealing with non-English charsets in gpsbabel and on the iPod. That wasn’t my personal itch that needed scratching, but it was someone else’s. Working together, everyone itches less :)

Released a bug-fix update to gpx2ipod tonight. Version 1.1:

No longer generates errors when encountering caches with slashes in their names. Now works properly when installed in a path containing a space (such as “/Applications/GPS Apps”).

gpx2ipod is also listed at VersionTracker.

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.

This is the official support / comment page for gpx2ipod.

Update: gpx2txt has been superceded by gpx2ipod – please visit that page for up-to-date info and discussions.

Downside of geocaching: The time it takes to prepare notes, making sure you’ll have access to hints and other people’s logs when you get there, etc. And the printing it requires doesn’t feel good from an eco perspective. All this data is available in .gpx files on geocaching.com, but most GPS units won’t display that data.

Paperless caching is where it’s at, but generally assumes you have a PDA. So what if you have an iPod but no PDA? The iPod has this much-overlooked “Notes” feature – mount an iPod, look in the Finder for the Notes folder, and drop in text files.

Amazingly, I haven’t been able to find anything that does this cleanly on the Mac. MacCaching is interesting, but (strangely) sends entries to Address Book rather to Notes, and doesn’t preserve any of the metadata you need on the trail. The workhorse utility gpsbabel is able to convert .gpx files to plain text (usable with iPod Notes), but the GUI version isn’t capable of batch operations. So I wrapped a shell script around the command-line version of gpsbabel to help Mac users do paperless caching with an iPod.

gpx2ipod takes a folder full of .gpx files and converts them to plain text, then injects them directly into an iPod’s Notes folder.

In the future I’ll try and re-package this as an Automator action, no Terminal required.

Update: Version 0.2 is now available, and handles both individual .gpx files and Pocket Query-generated multiple-cache .gpx files.

Update 2: gpx2txt has been completely rewritten as gpx2ipod – now much more user-friendly, with stored preferences and all kinds of bells and whistles.
