We had a great first day of map hacking in Seattle. I'd like to especially thank Martijn van Exel for creating maproulette.org/battlegrid. Our group is attacking the misaligned roads in Washington State using Battlegrid. For those that haven't used battlegrid, it is a visual tool to find difference between OSM roads and current Tiger data. We are finding that the Tiger data is better than OSM, especially in rural/outstate locations. But Tiger data isn't perfect either. Hopefully down the road, the US Census Bureau can use our data to improve their data.
I would also like to thank Tableau Software for hosting this weekend. -- Clifford OpenStreetMap: Maps with a human touch
