My favorite camera (Panasonic Lumix DMC-TS3) is waterproof (40 ft depth) and shock resistant ... and has a built-in GPS, compass, altitude, and barometer.

The GPS displays DD MM SS.ss format for latitude & longitude. Its only really useful if you have a paper map with matching gridlines ... and you know how to use them.

The camera provides names of the local city, landmark, ... but its pretty rough.

The compass only has eight compass points (N, NE, E, SE, ...). Its rough compared to a quality baseplate compass, but still better than nothing.

The altitude/barometer feature seems kind of iffy to me, but it might help. It auto-adjusts to give altitude, but I'm not sure the details of how it works.

The barometer could give some indication of weather changes.

Oh, and the video would allow my to record my last will & testament and my goodbyes if the worst happens ... in high definition.

I'll sometimes carry a Tamrac Zipshot tripod. Picture a 44" tall tripod made out of aluminum tent poles. Its plenty strong enough for my little camera, but its not nearly as strong as a fullsize tripod. Still, it would work for shelter support, a splint, a walking stick, defense against angry critters, ... The elastic cord that holds the "poles" together could be removed and be of use too.
