  1. Community Generated Map Data - Passive Vs. Active / Teleatlas Vs. Openstreetmaps

    by , 06-25-2009 at 10:14 AM


    There has been a lot of discussion about community generated maps. Cloudmade and openstreetmap have made immense progress, but their big drawback is that it required active user input to have the data be routable or reliable. Teleatlas has jumpstarted community generated maps by releasing a paid passively generated database that has been created and augmented by free passive user inputs. (teleatlas press release )

    In this Youtube interview Rik Temmink boasts 7 million reports in 18 months which have generated 1 trillion gps measurements on the road network. He describes the beauty of passive user inputs.
    The big drawback here is that Teletlas is now charging for these maps generated by their users. Why can't we hack our PDAs, phones, and other devices to create free maps? Most people don't think about the super high costs of map data. Hopefully the community can unite:

    • Collecting and sharing GPS data
    • Writing an algorithm to process this data into routable and usable information
    • Cleaning up open source algorithms to use this new data
    • Make the data free and globally available

    There are a lot of business and innovation blocks created when you have a monopoly of map data providers(Teleatlas/Navteq). How do we fix this?

  2. Via makes ivp-7500 automotive platform? Hmmm. We think Not.

    by , 06-25-2009 at 08:00 AM
    Back in march VIA announced the new automotive ivp-7500 (press release ). The announcement got some press from slashgear , crunchgear and has spurred discussions on our forums . Via claims onboard support for Bluetooth and GPS, which in all reality appear to just be add on modules. It seems like VIA took an off the shelf board, slapped on a few modules and rebranded old tech to create the appearance of an automotive solution. This might be perfect for a hobbyist or an R&D lab but you can forget about auto provider shipping silicone with a 0c-60c spec. If someone from VIA would like to explain the press release in more details, please post on the forums or e-mail us. We would be happy to write some revised commentary if there is something we are missing. Talk about this Blog post on our forums.


    Continue discussion here on our forums.

    Embed this video



    mp3Car's Rob Wray interviews Mark Schunder about Ford Sync Version 3

    In this video we take a ride with one of Ford's engineers to give you the technical side, and much less the marketing pitch for Ford Sync.

    Ford sync version 3 will give you the ability to speak to your vehicle and get services such as turn by turn directions, sports and weather.

  5. Green Eco Routing, Navigation and your car computer

    by , 06-16-2009 at 09:50 AM


    Some intelligent forward thinking researchers over at Hitachi, Xanavi, and Nissan have collected some data on ecological green routing that claims a 9% fuel cost savings on a test route. This technology is still in its infancy, but this is a perfect example of where a car computer can be used to accelerate development and deployment of technology. Implementing ecorouting will require Intense processing on the client or cloud for the complicated routing algorithms that factor in all the newly available data points:

    Traffic & Flow speeds

    Elevation changes and altitude

    Road quality (smooth vs. rough)

    Wind (eventually)

    The cloud or development computer can also be used to coach the driver into more efficient acceleration and braking techniques which a lot of hyper milers are already using.

    Eventually I imagine this type of data would help local governments prioritize road resurfacings and traffic control timings to help their citizenry become greener.

    It seems like one of the key pieces to making this work would be accurate elevation Data. The paper I mentioned above used 50m resolution data from the government. One of the key data providers for elevation data seems to be intermap with 5m horizontal resolution and +/1 1m vertical. Check out their comparison chart to NASA data.
