Why open source

Resiliency Maps contribute to and are powered by OpenStreetMap, a community-driven, free, editable map of the world backed by the not-for-profit OpenStreetMap Foundation. Our entire toolkit is open source, ensuring that the maps produced will be available to anyone who wants to use them and never subject to the bottom line of a for-profit company.

Preparedness is a shared responsibility; Resiliency Maps can be added to or edited by people across the city to provide information specific to where they live, work or go to school. The crowdsourced nature of Resiliency Maps means they don’t require a stable group of technical administrators or rely on a single group of committed volunteers to stay up to date.
