Join the Million Neighborhoods Initiative and spread the love this Valentine’s Day by

helping more than five hundred neighborhoods in Lagos, Freetown, and Monrovia

improve their maps.


Thursday, February 14

11:00am – 6:00pm

Searle Chemical Laboratory, Suite 240B

5735 S Ellis Ave, Chicago IL 60637


Pizza will be provided. Come for an hour – come for the day!

No prior knowledge of mapping necessary.

Only your laptop and enthusiasm! 


Mapping can directly impact some of the most vulnerable populations in the world. Urban poor communities in the Global South are using maps from OpenStreetMap to improve their living conditions.

How the Mapathon works:

  • Bring your laptop
  • Review map data on OpenStreetMaps
  • Track the neighborhoods you’ve completed!


We’ve put together a list below of links and tutorials on OpenStreetMap and how it works.

However, please note that no training is necessary for the Mapathon, and our Institute Fellow Anni Beukes will be doing live demonstrations through the day.
