How many times have you tried to give someone directions to your house or a meeting by sending them a link to Google Maps, MapQuest, or a similar service? How often do you find the maps produced by those websites are, ahem, less than accurate?
It turns out that most GPS and online mapping services pull their data from two services - TeleAtlas and NavTeq. They each have reporting tools for locals to help them provide the most current map data.
