TomTom Mapping

Part 1 - Map Geometry TomTom Mapping Van
 



This is the first of a series of 5 videos examining the mapping processes for TomTom maps. We look at the way the data is collected, processed and amended. This video looks at the TomTom mapping van collecting the core data for the base map.

Part 2: MapShare

 



This is the second in a series of five videos looking at how TomTom make the maps for your SatNav. This one focuses on the way TomTom users come together as a community and provide the data to help TomTom improve their maps and services.

Part 3: IQ Routes

 




  The third article in our series of How TomTom make digital maps looks at routing. In particular I am looking at the IQ Routes technology that TomTom introduced a few years ago in an attempt to ensure that users are provided with the best routes possible.

Part 4: HD Traffic

 




The final piece of the puzzle in the making of TomTom's maps is the dynamic attributes assigned to each road segment. By this I mean the real-time traffic information. Back in 2008 TomTom announced the then all new GO 940 Live SatNav. This had their latest innovation real-time live traffic known as HD Traffic. This fourth article in the series of How TomTom Make Digital Maps looks at how this traffic information is collected and distributed to the SatNav devices.

Part 5 : Map Changes



 



In the previous articles in this series we have seen how TomTom source their data, how the community provides input to improve the maps, how probes have been used to analyse the data, and how traffic information is collected. This final part of the series looks at how all these pieces are put together to manage changes in the mapping data.

As we have mentioned in previous articles there are many data items captured and entered into the main TomTom database. Of course collecting the data is just a small part of the process. With hundreds of billions of bits of data it is impossible to process each and every one as an individual item. This is where the back end systems come into play.

The TomTom maps are maintained by an online system known as Cartopia. Cartopia is a browser based editing system that allows a map editor to view many different items of data related to the area that they are working on. It also allows changes to be made and committed to the master database for inclusion in the Map Share updates or the next full map data release.
