Public Mapping Project

The drawing of electoral districts is among the least transparent processes in democratic governance. All too often, redistricting authorities maintain their power by obstructing public participation. The resulting districts embody the goals of politicians to the detriment of the representational interests of communities and the public at large.

We seek to change this power balance by making it possible for the public to draw the boundaries of their communities and to generate redistricting plans for their state and localities -- through their web-browsers. The Public Mapping Project is developing District Builder, an open source software redistricting application designed to give the public transparent, accessible, and easy-to-use on-line mapping tools.

This technological innovation will enable greater public participation where redistricting authorities solicit public input. Where redistricting authorities are not responsive to the representational needs of the public, plans drawn by the public may be used as a yardstick by which to compare a redistricting authority’s plan against. And where the courts must step in when the regular redistricting process breaks down, judges will have a greater menu of options to consider.

Also pictured from left to right are Antia Earls of the South Coalition for Social Justice, Tom Mann of the Brookings Institution, Norm Ornstein of the American Enterprise Institute, and David Wasserman of the Cook Political Report. Tom Mann and Norm Ornstein graciously served as judges for the Virginia Redistricting Competition.


Full Public Access to Version 1.1

All members of the public are invited to try out the newly released version 1.1 of the District Builder software. We recommend that you visit web sites of organizations and governments who are providing public access to our software. We hope to announce other partnerships in the future.

The software can be used for any state or locality. We are working on incorporating other states' data into the software and list the currently available states. At this time, we are not providing web hosting for these other states other than for educational purposes, courtesy of Amazon in Education. These pre-configured versions of the software
can be hosted through your own Amazon Web Services account. Those interested should follow these instructions.
