Smart Redistricting

As a cost-effective and time-saving solution, iRedistrict® can dramatically save the workload and improve the outcome quality of redistricting projects. iRedistrict® excels in its capability to leverage user inputs (such as communities of interests, existing boundaries, etc.) and powerful computer algorithms, which can generate high-quality redistricting plans that meet both mandatory requirements and user-specified preferences.

iRedistrict® has online edition and desktop edition.

Community of Interest Collection

COI Collection

COI Collection is an online service for collecting COI (Community of Interest) data from multiple users simultaneously. It allows users to draw COI in real time, save records with descriptions and timestamps, and export data in Shapefile or Block Equivalence File formats. Users can create, save, and open COI projects, ensuring efficient collaboration and organization in COI mapping.

FAQ

Does iRedistrict support starting from an existing plan

Yes, with iRedistrict, you can load an existing plan as a boundary, then ask the software to produce plans minimizing the cross of this boundary. It supports working with multiple boundaries. That means, you can minimize the cross of an existing plan and also administrative boundaries.

How can iRedistrict produce 0-deviation plan?

One solution is to set higher weight and very low threshold on population equality before running the optimization. After producing the plans, lock the districts that have 0-deviation and rerun the redistricting optimization. Repeat it several times, you will get 0-deviation plans. Another solution is to fine tune the plan boundaries. Pick a plan and mix it with the block layer to produce a polygon file that has blocks around the plan boundaries. Then run redistricting optimization on this file. Repeat the first solution if necessary.
