I need to make relatively precise measurements, to the nearest half meter, of locations on my field site, which is on the floor of a Mediterranean cove (not more than 10m deep). One possibility is to swim on the surface above my locations and use a GPS to record the points - but so far my older-model GPS's have not been accurate enough for this. I'm leaving in about a week, and just recently I was reminded that technology may have advanced to meet my needs, even since last year! Can anyone update me on the latest and greatest (waterproof) mapping instruments out there?

A researcher at my workplace has asked for help finding examples of his topic, early examples of "GIS (Geographic Information Systems) or GPS (Global Positioning Systems) technologies in film and TV", "examples of early precursors to map related technologies". I found someone else's Ask from earlier this year that hits on some likely ones, but he's on the lookout for older and more diverse instances if you can think of any. More details and examples below the fold! [more inside]

Suggestions for an intuitive mobile phone with GPS, camera for directionally-challenged adult daughter.
I need a suggestion for a mobile phone that is very intuitive, has GPS and is a camera phone. Bonus points if it's kinda like OnStar, speaking directions aloud, and is affordable--under $250--although I don't know if that is possible...you tell me. [more inside]
So I love my blackberry pearl 8100 but I've had it with all of RIM's bluetooth crippling and limitations. I want a phone the exact same size with a great keyboard that does email, bluetooth and works with T-Mobile. Ring it up MeFites. [more inside]
Roadtrip technology. Which would you prefer, high-tech solutions (web-enabled phone/Palm, laptop, GPS) or low-tech solutions (maps, AAA Triptiks, GoogleMaps printouts) or some combination? [more inside]
