Instead of just saying "depending on its view of the sky, it can be off by as much as 100 yards" how about give examples of where it was within a reasonable range of accurate (most decent GPS units claim either a 3 or 10 meter area for accuracy)? 300' can be make a huge difference for locations, depending on terrain. Could be on different sides of a lake, river bed, on the top of a cliff, or a good distance away at the foot of it, etc...
Personally, I'd prefer one that adds the information for me without having to run additional software to get the job done. JPG compatibility is fine, since I'm not about to upload RAW files to my site (I will send to paying customers, but that's a different story all together)...

100 meters is far worse than most regular GPSes. My handheld is rarely more than 30' off except in the bottom of a narrow canyon, and almost always within 10'.

Regarding geotagging, if you carry a handheld GPS with you (which I personally do most of the time when hiking or sightseeing), and your camera's time is synchronized to the GPS time, you can upload its recorded track to your Mac as a GPX file and use one of several free utilities that will geotag your photos using that track. I use GPSPhotoLinker routinely and have been very happy with it. It's not that much of a problem to do for me because I already like to save my GPS tracks anyway (for showing on Google Earth, for example) so all I do is drag my track file and my folder of photos into the application and voila, they're all tagged.

For people who start off their workflow in the RAW format, Nikon's incomprehensible Windows only proprietary RAW format renders the newly released P6000 Coolpix's gps functionality useless to Mac & Aperture users.
Hope Ben writes about this in a future review & perhaps compare it with Canon's G10 & elucidate why Canon failed to also include built-in gps with it.

Eye-fi memory card will automatically do this (although it uses surrounding wi-fi networks to figure out its location a la iPhone 1st gen)

That's beyond useless when it comes to photography. Not only will you not get an accurate result WHEN you have enough open AP's in your [close enough] area, but you're locked into a very narrow range of where you'll be able to [even think about] using it. TRUE GPS is the only way to go.

I would prefer a tagger that can make the changes to the files directly, via the card connecting to it, so that it's both platform, and software, independent. It would also be good if the tagger device had a separate battery (coin type) so that once you set the time, you don't have to check it every time you go to use it.

I'm still looking for an explanation from the author as to what conditions made the one tagger so inaccurate. Are we talking high mountains, with very little sky visible, or was it also in open fields, with miles of clearance?

What there needs to be is an iPhone 3G app that just creates as log like the ATP photofinder then sends it to your computer where an app can match the log and exif times. This would also have the benefit of time changing when your camera's time is off.
This app could even possibly be an automator action: Grab photos > get time difference > get log file > add exif to photos > import to iPhoto / Aperture.
And if there were an easy app like that it would work with a regular GPS that creates log or a Windows Mobile / Blackberry / other smartphone that has GPS (most phones do now).

Also - check out EveryTrail www.everytrail.com - their iPhone app lets you geotag pictures during your hike, bike or walk and then automatically posts a slideshow

And another site...allow me to disclaim, I created the site myself to fulfil a task I personally needed, for occasional use and older images of varying filetypes. If you visit http://geostamp.me you just place a marker on the map, upload an image and it returns the geocoded version. Obviously you'd never use it for batch coding, but for one-offs or corrections it may suit.

Stanton's software free iPhoto plugin, iPhotoToGoogleEarth, is a dead link.

Another basic but easy-to-use GPS logger that is Mac-compatible is the AMOD AGL3080. It mounts directly as a USB storage drive and its standard format NMEA 0183 logs can be used in many different mapping and geotagging programs. I reviewed it at
http://scilib.typepa...agl3080-ma.html
I also have a list of all the Mac-compatible loggers I know of at

Hi!
Thanks for mentioning HoudahGeo in your recent article about photo geocoding.
I would appreciate if you could still correct the spelling of the product name. It is HoudahGeo. One word, with a H just before the camel case G.
I would like to clarify that while HoudahGeo does not require the user to have iPhoto, it actually integrates directly with iPhoto, Aperture and Lightroom.
Actually, I believe that HoudahGeo is the premiere photo geocoding solution for the Mac. It works both for automatic GPS-based geocoding and for manual map-based geocoding. It is designed both for users who want to geocode images for archival purposes and for users for whom geocoding is part of the publishing process.
Please let me know your email address, so I can send you a NFR license.
Best,
Pierre Bernard

I'm not aware of my server being offline recently, you must have just hit it at the wrong second, the site is live and kicking

There is a new iPhone app available called GeoLogTag. As it's name suggests it's a geologging and a geotagging application. It integrates with your Flickr account(s). Accuracy is around 10 meters which is pretty cool. You can find more info about it at www.galarina.eu/GeoLogTag.
