Hear hear.
Suppose the following. Fortunately, you're in a remote bit of Australia. Unfortunately, you've broken a leg. Fortunately, you have a rescue chopper on the phone. Unfortunately, you dropped your GPS in a river. Fortunately, you know where you are, and you have a standard topographic map, so you read them a grid reference.
They won't be able to find you.
I realise that they're from the government, and they're here to help. Even so ...
- prodigal_erik 16y agoI don't understand the problem. Does the map rely on a different datum than WGS 84 (which GPS uses) for latitude/longitude? http://en.wikipedia.org/wiki/World_Geodetic_System http://en.wikipedia.org/wiki/World_Geodetic_System
- thisrod 16y agoIf the datum mattered, we'd declare victory already. Aviation GPS units use latitude and longitude, the maps use UTM, and the pilots have no way to convert. D'oh!
