Possible to use existing map sources for GPS?
I've been trying to figure out ways around the lack of GPS software for linux. It seems to me that the problem isn't that there is a lack of programming tallent when it comes to making a program but rather there is a lack of usuable maps as a data source. The tiger data is always thrown around but when one considers how primative that data is and how much effort it would take to get the data to look decent, it just took to much work.
So the question is, could you make a program that would be able to access exisiting map data sources? Streets and Trips software can be very cheap and might serve as a good source of map data. If you could build a Linux program that would be able to make use of the map data then we could have a solution for GPS and even if you had to pay a few bucks for the maps it would be worth it. Sure it might not do directions and stuff but for now I'd just settle for some plain old positioning.
At times like these I wish I was a software engineer and not an aerospace engineer...
