a wiki type GPS library ??? Pretty much everyone has a GPS navigation system now, whether it be in their cell phone or in their car. with all the new houses being built and new highways a lot of times you find yourself in the middle of a field according to the gps because that new road has not been surveyed yet. i think it would be useful to have some kind of system where people can submit roads to a library the gps can read from. that way if a bunch of people live in a newly built development they can all submit information to the database on where the roads are and would not have to explain to their relatives during holidays how to get to their house (what a pain). and if the system was set up like a wiki there would be enough people to confirm what roads are true and constantly update it. any opinions on this? ps i dont have a real good understanding of GPS systems in the first place so this is just for fun.
