Mark-a-Spot is a distribution for public civic issue tracking and crowdmapping. It's shipped with an included Open311 GeoReport v2 Server and a Bootstrap/Radix based responsive sub theme. You can integrate Mapbox, OpenStreetMap, Google Maps, ArcGIS and GeoServer.
This distribution is in use at several local government agencies like the cities of Cologne, newspapers or as a waste management platform in Maputo, Mozambique, a project sponsored by the World Bank Group.
The code for Mark-a-Spot is maintained in two separate repositories: github and drupal's own repository.
