Best Setup for Mapping in Undeveloped Countries?

Floodimus asks: "My girlfriend lives and works in West Africa and on my next visit she has asked me to help her do some mapping of uncharted villages. I want to make this study really accurate and useful, so I am thinking about using high tech and low tech resources such as GPS and good old fashioned compasses, but I was wondering what the Slashdot crowd would recommend for GPS hardware (does GPS equipment from the US work over there?), field equipment, mapping software etc. I use both PCs and Macs and would like the software to run on the Mac, but it doesn't have to. What's the best, most rugged stuff you've used? Where are some resources that would help me out?"

    does GPS equipment from the US work over there?

    Ok, a quick explanation of how this stuff works is in order. GPS stands for Global Positioning System. The system consists of 24 or so satellites that provide nearly complete coverage of the globe at any given time. By capturing signals from more than one of these satellites, your receiver can calculate your position based on the last known position of the sats. Thanks to the precision and accuracy of modern electronic hardware, this calculation can be accurate to within 20 meters or less.

    So to answer your question, of course GPS equipment can't be used over there! They use 220V AC and we use 110V AC. Where do you think you're going to find a charger? You need to get yourself a step down transformer, or you'll never be able to charge the equipment! Yeash, what are they teaching you kids these days?

      Yeah, cause every uncharted village has a ready supply of alkaline batteries in AA, AAA and AAAA sizes.

      > now, if the military found that the enemy was using GPS to deliver bombs and such, of course they'd turn it off,

      I wouldn't turn it off, I would re-route it 8-)

    No. We made sure to send Africa very very degraded signals. How much does a meter of accuracy matter in a desert or jungle anyway?

    I travel in the US with a GPS in my laptop bag (Garmin GPS V), but depending on where you travel in the world, you may want to insure it doesn't violate any local laws. For example in (don't mod me funny) Ex-Soviet Russia it is illegal in most cases to have GPS equipment. You can be thrown in jail and it may not be pleasant.

    You travel to Africa to get to your girlfriend?!? Dude, either you are TOTALLY pussy-whipped, or she's totally hot and you're a genius for getting her away from any potential competition by sticking her out in the boondocks. ("A 'bird' out in the bush is worth two in a developed country', I guess they could say).

    Fortunately, the Motion Picture Assoc. of America didn't forsee GPS's ever being used for any kind of movie viewing... so they didn't press to get region-coding into GPS's, like they do with DVD players. :)

    For the price of two regular laptops, get a Panasonic Toughbook. It will still be useable after exiting the far end of the digestive tract of the alligator that eats you.

    Are you kidding? I'm writing this from a Panasonic CF-29...you could close it, beat the alligator to death with it, open it back up, and continue working. They're pricey, but great computers.

    And yes, if one has the money for it, I would heartily recommend one of these for such a trip.
