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?

Public health doctors are apparently "hopeless" at using traditional media (BMJ 2003;327(7422):1056); it's probable that their use of new media is even worse. WhoIsSick have come up with the idea to use Google Maps to track illnesses in local communities. Perhaps this is something that public health physicians should explore as a means to both inform populations about disease patterns and for encouraging their participation in reporting?

When writing about geocaching I mentioned that I'd heard of geotagging—but I hadn't made use of it. I've also posted about various ways to keep track of places you've been, including utilising Google Maps. I like to catalogue my travel pictures in iPhoto, but know of no way to integrate iPhoto and Google Maps. But you can use Google Earth to display geotagged photos in your iPhoto Library—even if you don't have a GPS device to record coordinates.
