Just bought a new TomTom with a 30-day latest map guarantee? Don't download any map update as prompted by TomTom HOME on the day you register your device. Why not? Because if TomTom do release a new map in 30 days time, you won't be allowed to download it. You may still be within 30 days, but you will have the map that was current on the day you got your device. If, however, you carefully count to day 30 before downloading any map updates, you will get the latest map as of that time. The ambiguous guarantee is not for the latest map within 30 days—it's for a map within that period.

After David rekindled my interest in geotagging blog posts with Google Map integration, and Dave's photo tracking experiences convinced me to revisit geotagging photos, I posted An ABC of geotagging photos on the Mac. In that article I considered questions relevant to selecting an automatic geo-location system, naming most of the few Mac-compatible devices available. I recently purchased a data logger to overcome the pain of manual photo geotagging and dispense with the hassle of a DIY solution.

If I told you I was using a GPS photo tracking system for geotagging photos from my Nikon D70 that stored track logs and waypoints to 1GB of memory, exported in GPX format, and connected to my Mac via USB or Bluetooth—you'd be right to wonder if I was making it up. It's not fiction, and nor is it new tech either. It's a "make do" solution I put together from gear I'd already been using for several years and with £0 new investment. Given poor Mac support in the data logger market, such a system is surely a good way to experiment on the cheap before shelling out on yet more battery-operated gadgetry.

The iPhone SDK is out in beta, and a GPS module for iPhone and iTouch from gomite is "pending". However, as Wired observe the ban on background processes for third-party apps "eliminates the possibility of a geo-data updater running in the background, reporting your location back to a web service". This might also make it impossible to use the iPhone's camera app in conjunction with data logging software for geotagging if they can't run simultaneously. What happens if you need to take a call—would the logger have to quit?
This article considers geotagging photos from a Mac perspective, looking at automatic and manual methods, and explaining terms such as data loggers, track points, waypoints, and routes. It lists OS X software options for connecting to data loggers, converting track log formats, geo-locating photos, and writing that data to EXIF for both raw and JPEG images. It also covers the importance of time synchronization, what you can do with geotagged photos, workflow, choosing a data logger and controlling it from your Mac.

Geotagging (or geocoding if you prefer) is the act of associating your content (blog posts, photos, feeds, etc.) with a geographic location (e.g. via latitude and longitude co-ordinates). Thus tagged authors can "mash" their content together with the likes of Google Maps, or the Flickr Map if photography is your thing. However, co-ordinates are typically encoded within metadata (or microformat) tags making them visible to machines but hidden from people. We have de facto web standard icons to help identify feeds, OPML, and sharing—so why not for geotagged content?
