The Ebola outbreak has been devastating in Sierra Leone, Guinea and Liberia and Doctors Without Borders/other aid organizations need all the support they can get. This is a volunteer mapping event using OpenStreetMap to provide detailed digital data to aid workers on the ground in West Africa.
Anyone can join, even if you have no experience. There will be computers provided but you can bring your own laptop if you'd like. There will also be bagels.
See blog posts on previous mapathons for more information about the project:
