Over the weekend of 08-March-2018, 309 volunteers from around the world participated in a Mapathon to map structures in Tanganyika Province in the Democratic Republic of Congo (DRC) in support of the Global Polio Eradication Initiative. The event was hosted on the World Heath Organization’s (WHO) ArcGIS Online Platform with information about the event being shared via an Esri Hub page.

Volunteers from a variety of organizations joined the event including WHO staff, Centers for Disease Control (CDC) staff, GISCorps volunteers, Esri employees, Standby Task Force volunteers, and others. At the conclusion of the Mapathon, over 385,000 structures had been mapped in Tanganyika Province, with 3 priority districts mapped to 100% completion. The data was concurrently validated for accuracy  in the background by GISCorps volunteers with GIS and remote sensing expertise.

End of Mapathon Statistics

In 3 separate Mapathons over the course of the last year, volunteers have mapped over 1.2 million structures in DRC and Somalia in support of the Polio Eradication Initiative. WHO, CDC, and GISCorps managers and technical specialists have built and refined the applications over time to make the process as streamlined and easy to use as possible. High resolution imagery has been generously provided by Digital Globe. A previous post on the 2017 pilot Mapathon can be seen at this link. The structure points and statistics are now being used in printed mapbooks on the ground in DRC to help guide the creation and refinement of vaccination microplans.

GISCorps would like to thank our partners, WHO and CDC (GRASP) , for reaching out and involving our team in these projects. We would also like to thank the technical supporters of the project: Esri Non-Profit and Esri Disaster Response Teams for providing software and support, and Digital Globe for providing imagery. And most importantly, we’d like to thank all the volunteers for being involved in this valuable project to help eradicate polio.
