The Dead Ushahidi site is a bit meta: it documents, on a Crowdmap map (that's the free online tool for anyone to create a crowdsourced map of anything) Crowdmap efforts that are "dead." The "Dead Means Dead" page explains what's needed for a non-dead, aka, useful, Crowdmap, then details what criteria can put an existing map in the dead pool.
To end up in the Ushahidi cemetery, one of the following is true about map:
- No one (let alone a crowd) has submitted a report to your map in the last 12 months.
- For time-bound events, like elections and disasters, the number of reports are so infinitesimally small (in relation to the number of the community the map is targeting) that the map never reached a point anywhere near relevance. (Our measure for elections is, for instance, # of submissions / # of registered voters > .0001).
