Mapseed is a platform that allows anyone to create community-driven maps on the web. These maps allow users to report issues or submit ideas and respond to the issues & ideas of others. Combine user-generated content with external data overlaid on the same map to allow anyone to see what’s going on in the area at a glance: https://github.com/mapseed/platform
Mapseed was originally developed to empower community members to stay informed and track the cleanup of toxic waste along Seattle’s Duwamish River. HeyDuwamish.org runs on Mapseed. It’s now used for several other community maps
The Mapseed platform is a fork of Shareabouts, which was developed by OpenPlans before they closed in 2015. It is a «spiritual successor» to Qué Pasa Riachuelo?.
