Digital map maker Tele Atlas announced today a new version of its database, Tele Atlas MultiNet 2009.02. this is the first map database of the Belgium company to contain new and adjusted roads based on passive feedback from map users. It now contains new roads, as well as roads with adjusted geometry, detected or verified in part using real world GPS measurements on thousands of roads from TomTom customers. These users have opted in to provide anonymous data (GPS tracks) to TomTom via the desktop application TomTom Home.
The number of customers providing this passive feedback is much larger than the size of the TomTom Map Share community (over five million participants) - the latter requiring users to input data on their devices. As a matter of fact, through these passive uploads Tele Atlas gathers 80 million kilometers of GPS tracks on a daily basis in Europe and 20 million in the United States.
