At Rootscamp13, I gave a presentation called “Map Anything” that discussed how we combine common political geography identifiers and shapefiles to create a political data visualization revolution. Here are some links I promised attendees:

• The OCD Division Identifier repository, along with the Google Group, and division id validator
• The Google Civic Information API, along with an intro article, and sample app.
• And, new within the last 24 hours, a GitHub repo of post-2010 precinct shapefiles.
