OpenStreetMap Data in Production + Labeling OSM Streets with Foursquare and Mapreduce - David Blackman from OpenStreetMap US on Vimeo.

So the goal is to make this data accessible and begin using it in our import pipeline, given that data quality is not a major barrier. If the quality is not sufficient (though we think it's already pretty excellent), exposing the data to the community will hopefully encourage improvements to it.

Here's what we need to do...

Story Estimate Priority Status Notes
Implement polygon extraction 3 0 done
Make it faster 2 0 done
Split output into admin_level files 1 0 done #2
Chef-ify extraction process and setup recurring runs (identify list of supported extracts) 1 0 done
Create simple website for download of extracted data 3 1
Normalize the data: find common set of tags and add areas with non-standard/incomplete tags to error output 2 1
Write blog post 2 1
Fork admin-lookup and populate with osm polygons instead of quattroshapes 2 2
