A device like the Tom-Tom navigation devices can gather incredibly accurate GPS paths that when combined with the user feedback of Tom-Tom and Google Maps users and matched against satellite imagery can allow TeleAtlas to make more maps changes in less time, less expensively than sending out cars and drivers. This capability will grow, going forward, with the introduction of navigation devices that offer a 2 way connection back to TeleAtlas and TomTom. The volume of data, the nature of the data and the timeliness of the data could mean that Map errors in Google could be updated in a 1 to 4 month time frame going forward, rather than the traditional 6-9 months they have taken in the past.
The recent TeleAtlas update includes 50k map edits from community data to the Maps.
