There are many sat-nav systems on the market, but who provides all those detailed maps for them?

That question was answered on the tele Atlas stand at the show, where the firm proudly showed off its hi-tech skills.

The firm employs nearly 2,000 people worldwide updating maps and is continually improving its databases. now tele Atlas Logistics has been launched, a commercial vehicle system which automatically calculates not only the quickest route but the safest too, avoiding roads with weight restrictions and low bridges.

Database operations manager Allan Rasmussen said: “Facilitating efficient and safe road routing is ever more important. By using our fleet of mobile mapping vans and data from the ordnance survey, tele Atlas has rich and accurate routing information.”
