CALIFORNIA CASE STUDY
Resocatec was contracted by the State of California to develop a web-based interactive mapping tool that allows participants to draft and submit Community of Interest delineations to the California Citizens Redistricting Commission. A Community of Interest, as mandated by the California Constitution, is an important building block in the decennial redistricting process. Communities of Interest allow citizens to identity their common geography (e.g. population area, economic activities, trade and social interactions) — insuring communities are included whole within single districts for effective and fair representation.
Our solution, an interactive open source map titled Draw My CA Community (featured in the images below), offers guests and registered users the means to delineate their community. Built upon nested Census boundary geography (i.e. County, City, Tribal Area, Tract, Block) — citizens first specify the name of their community and then interactively “draw” their Community of Interest by selecting Census statistical area geography at their chosen scale.

Seamless open source base geography, cloud storage of delineations and Census data libraries reduces the costs, data management, facilities and personnel clutter that may otherwise have been required of the Commission.
Citizens choose from several drawing tool options to interactively select their Census geography and finalize their submission (Figures 2, 3, 4, 5 below).
