A post on Slashdot covering some marketing information from TomTom prompted me to check out the quality of OpenStreetMap, widely rumored to be the primary source of data for mapping in the next version of iOS. I typed in my zip code and scrolled around a bit. I quickly focused on a housing development within a couple of miles of my house.
It appears that OpenStreetMap is quite a few years behind Google when it comes to Castle Hills. Entire completed neighborhoods are just missing. That’s a little scary.
