It was National Holiday yesterday where I live, so it explains sharing this weekend story on a Tuesday, discussed by Slashdot: How Satnav Maps Are Made.
Their summary: ""PC Pro has a feature revealing how the world's biggest satnav firms create their maps. Nokia's Navteq, for example, has a huge database of almost 24 million miles of road across the globe. For each mile of road there are multiple data points, and for each of those positions, more than 280 road attributes. The maps are generated from public data and driver feedback, not to mention its own fleet of cars with 360-degree cameras on the top.There's an IMU (inertial measurement unit) for monitoring the pitch of the road, and the very latest in 3D surface-scanning technology too. This light detection and ranging (LIDAR) detector captures 1.3 million three-dimensional data points every second, mapping the world around Navteq's field vehicles in true 3D. The feature also investigates whether commercial mapping firms will be replaced by open-source maps." That last line makes me think of the difference between conventionally published encyclopedias and Wikipedia; "replaced by" is an odd standard in a big marketplace of ideas."
We mentioned this type of possibility a few times in the past, and it's getting more and more real ; Slashdot it discussing a story named TomTom Satnavs To Set Insurance Prices.
Their summary: "TomTom has signed a deal with an insurance firm that will see its satnavs used to monitor drivers. Fair Pay Insurance, part of Motaquote, will use monitoring systems built into the TomTom PRO 3100 to watch for sharp braking and badly managed turns, rewarding 'good' drivers with lower premiums and warning less skilled motorists when they aren't driving as they should. 'We've dispensed with generalization's and said to our customers, if you believe you're a good driver, we'll believe you and we'll even give you the benefit up front,' said Nigel Lombard of Fair Pay Insurance."
