Danny Grobben (TeleAtlas) began the seminar with a talk about using the navigation community to build and maintain digital maps. TeleAtlas creates the maps that we see on a TomTom (GPS) but what fascinated me was how we, the TomTom users, contribute to the updating of these maps simply by connecting your GPS to the network and loading our comments. Such as “N1 now only has one lane” or “This road is now a one way road,” all these comments get verified and if correct all the other tomtom maps get updated. Our routes also get monitored so the head office actually knows if roads are active just by how many routes travel on that road. Who would have thought that we could actually help with the accuracy of the GPS maps just by driving to our regular destinations?
Our community contributions don’t end there, we also contribute to the Traffic updates that are loaded every 3 minutes on all the TomTom’s (the ones that have traffic alert layer). HOW? Well TeleAtlas is actually working with TRACKER and traffic alert companies to collect the most up-to-date traffic information. So on your GPS you will now know where the actual traffic back logs are happening and how long it will take to reach your destination. Your GPS will then provide you with another route which would be quicker. The data they have collected for the re-routing was obtained from TAXI drivers who travelled with GPS’s. So your GPS is as smart and as quick as a TAXI driver when it comes to re-routing. I don’t know about you guys but this makes me want a GPS. This would mean I wouldn’t have to call Ronaldo to find out how traffic is….or wait till the radio tells me there is a back log on the N1. You will also get crime alerts on the GPS, so now when I drive by Deipsloot I will be reminded to lock my doors. So are you thinking of getting a GPS? Read on.
The next presentation was by Geoff Green form Precinct Web. I was very impressed with Geoffs presentation on how you can set up a community base mapping project in support of disaster and crime management in Johannesburg. This could be done simply by mapping crime using an open source mapping system and Google maps. Crime clusters, plotted on a map, lead the police to find exactly how the criminals where getting into certain enclosed communities. In one case a storm water channel that went underground for several kilometres lead the police to where the actual problem was – poor communities in Alexandra. After this presentation I got inspired to set up my own community crime mapping site.



The whole conference really got me thinking about the life we are living in and the life we are going to be living in. I loved that GIS was advancing so much and I was in the “know how” of it but I really did get concerned about the future privacy levels. I was baffled when Etienne said at the end of his presentation something along the lines of “It is already written in the book of Revelations so you might as well buy into it now!” Brrrrrr I started to re-think my purchase of a GPS unit.
