Drive-by mapping: the technology behind sat nav

Posted on 22 May 2007 at 15:11

In this exclusive video report, PC Pro's Jim Martin goes behind the scenes with Teleatlas - one of the UK's major sat nav map data suppliers - to find out how maps are made.

We take a ride in a mapping van that captures all the data needed to turn the real world into what's displayed on your screen. Plus, we discover how maps may soon appear in 3D. Don't miss the forthcoming issue of PC Pro - out July 19 - where we'll be rounding up the latest crop of portable sat nav devices.
