See "The importance of place - GPS and photography",

for a camera with optional GPS receiver that orientates to the
direction of the image. Of course this will add 300.00 USD to 500.00
USD to your camera.

The following is an example of EXIF GPS tags and values:

[GPS]
GPS Version ID = Version 2.2
GPS Latitude Ref = North latitude
GPS Latitude = 39°54'56"
GPS Longitude Ref = East longitude
GPS Longitude = 116°23'27"
GPS Time Stamp = 18:07:37 UTC
GPS Date Stamp = 2003-11-23 UTC

The GPS described doesn't have a display, which accounts for the lower
price, and the long battery life. It isn't a full-fledged GPS at all,
just a way of recording time and position stamps, which many 'GPS
enabled' cell phones do for even less. In short, I am not impressed by
either the price, or the capabilities.

GPS enabled cell phones generally do their thing with the aid of data
provided by the cell sites they are normally listening to. Go someplace
without cellular coverage (or coverage that your phone is not compatible
with) and you'll get no position data at all.

On the other hand, this seems to be a full-fledged GPS receiver, in the
sense that it's capable of determining its position without outside
help. That makes it cost more, but worth more, than a cell phone's GPS
functions.

It's still not a consumer GPS unit with display and user interface; it's
just a position logger. But that's exactly what is needed to work with
an arbitrary digital camera. (It would be even nicer to have a camera
with integrated GPS receiver).

I seem to have missed something here. Does the GPS info attached to the
photo give a degrees coordinate or a an actual location? That is, does it
include something like an address? To do so presumably it would need a built
in map as well in. Otherwise it will give you what my navigation device
does, and that is a set of lat/ lon coordinates which to my mind is not
going to be all that clear to the average user.
