Crowd2Map Tanzania is a crowdsourced initiative aimed at creating a comprehensive map of rural Tanzania, including detailed depictions of all of its villages, roads and public resources (such as schools, shops, offices etc.) in OpenStreetMap for everyone to use.

We are mapping primarily on OpenStreetMap via Maps.me app on smartphones or tablets and directly editing openstreetmap.org on laptops.

See the full instructions about how to Get Started here.


You can:

  • Do OSM mapping online: we are currently mapping an area around Mugumu, where female genital mutilation (FGM) is prevalent. Find the task and start mapping on HOT task manager here (task #1788).
  • Map your area: download Maps.me app, log in with your openstreetmap username and add points in your villages. More details and instructions are here.

  • Participate in our mapathons! We have recently run a widely successful Triple Mapping Party, and are planning to organize more of these events! Check back to see what’s coming!

You can also follow our Twitter and Facebook accounts for more up-to-date news.

  • Organize your own mapping event! We are always happy to help if you’d like to organize a mapping day in your own area. Just drop us a line, and we’ll help how we can to make it happen!

The project was originally set up in November 2015 by Janet Chapman (LinkedIn), Communications Manager at the Tanzania Development Trust (London) and Egle Marija Ramanauskaite (LinkedIn), writer, researcher and educator in the field of Citizen Science (Vilnius), upon meeting at the Mozilla Festival 2015 & exploring options to involve Tanzanian schools into Citizen Science.


We are making progress during online events and mapping parties! Check the latest news on our blog!
