If you have never heard of crowd sourced maps, checkout our previous blog post here or an example of a growing Philippine map in timelapse.
At Nokia world 2009, Navteq announced they will be crowdosourcing map, routing, and traffic data. Twice has a good overview. Also see a recent Google's blog entry about google's crowd sourcing strategy.
jKontherun reports that iphone users can utilize but aren't contributing to Google's arterial data. Google was quoted as saying “The Google Maps application that comes pre-installed on the iPhone can display live traffic, but Apple devices do not participate in the traffic crowdsourcing.”
Talk about this on our forums
Navit is an open source turn by turn directions app using the free Open Street Maps.
It is important to note that both the app and the routing engine, along with the map data are all Open Source!
The app is in beta still and can be downloaded using Cydia.
Add this source http://szndvc.dyndns.org/cydia/
and then search for "navit"
You need a planet.bin file of the Open street maps data. You can use this http://maps.navit-project.org/planet.bin but they have a tool that lets you select a portion of the map to download.
That file will go on your iPhone at var/mobile/Media/Maps/planet.bin

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 dataMake 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?
