[HOT] Analysis of when mappers joined OSM

[Sajjad Anwar]

Hey Janet,

I tried to extract all changesets created with the hashtag
#TanzanaiDevelopmentTrust and merged with some user information for
their first edit. Here's a CSV -
https://www.dropbox.com/s/swr54ly2rg4zyw8/osm-changesets-tanzaniadevtrust.csv?dl=0
with 97,262 changesets.

I ran a query on the database that powers
https://www.mapbox.com/osm-comments/ and https://osmcha.mapbox.com/

Hope that helps!

Cheers,
Sajjad
