DistrictBuilder is web-based, open source software for collaborative redistricting.

Customizable open source software built by experts

DistrictBuilder was developed by leading redistricting experts at the Public Mapping Project. Whether you work for a state or local government agency, an advocacy group or you are a legislator, DistrictBuilder has been designed to provide you with affordable, easy-to-use, customizable redistricting tools that make the redistricting process more open and collaborative across agencies and with the public.

Open source license means it's both affordable and part of a community

Unlike proprietary solutions, DistrictBuilder is open source so you don't have to pay a license fee. If your team has the expertise, you can download the source code and build your own redistricting application. Or our software partner, Azavea, can work hand-in-hand with you to create the perfect application for your needs. And if we built a new feature for your application, it is immediately contributed back to the community of users. The more you add, the more we give back.

System Requirements

The software is built using several open source technologies including:

  • Django
  • Celery
  • PostgreSQL
  • GeoServer
  • jQuery
  • PostGIS

The software can be hosted in several environments:

  • Amazon Web Services
  • On Premise Installation
