[HOT] The evolution of humanitarian mapping within the OpenStreetMap community

Thu Dec 9 12:57:16 UTC 2021

This is great !!! I am interested in this ,especially,having stats of Local
mappers(in terms of City/Country location and Remote Mappers (Non-local
Community). What about deciding the geographical buffer of contributors to
a mapping task so contributors outside a buffer defined by distance or
boundaries are locked out from contributing to a task ,so as to ascertain
how long response is sure and when to escalate for more help.
I would like to test this in Nigeria and any other location as a developing
country where we are looking forward to a more sustainable OSM community .
