How political districts are drawn determines who gets elected. Unfortunately, the process of drawing districts often takes place behind closed doors, with little to no input from the public. DistrictBuilder is a free redistricting tool that empowers everyone to draw better electoral maps, all online with no need for desktop software. In this talk, Dan and Jeff will demo the latest release of DistrictBuilder, discuss how they built it, and highlight ways that everyone can be involved in fair redistricting.
You’ll learn how to...
- Advocate for fair districts in your community
- Design intuitive applications using maps
- Build tools that move geospatial analysis online
