UPDATE: Harry's blog write up

Past event details:

At this map editing mapathon event we'll be helping save lives by improving the map of the Phillipinnes and Vietnam on OpenStreetMap. If you're learning how to edit OpenStreetMap for the first time, we'll teach you!

Aid agencies currently deploying in the wake of Typhoon Haiyan are using detailed maps from OpenStreetMap to plan their logistics. By improving the maps we are not only helping in this disaster response, but also helping OpenStreetMap in their not-for-profit mission to map the world and release it as open data.

What you need? : Bring your laptop (works better if it's not a tiny screen, and if you have a mouse) We'll show you the ropes and teach you an exciting new skill

Nothing else?

If you want to give yourself a headstart:

• Sign up for an openstreetmap account
• Install JOSM the Java OpenStreetMap Editor

...and come along to the Open Data Institute at 6pm to learn more! Futher reading for the ultra keen:

• Head to LearnOSM.org to learn about how it all works
• Check out the Typhoon_Haiyan mapping coordination page and links to the "tasking manager"

This is a free event but with limited spaces. Get your name on the list to be allowed in. No need to print eventrbrite tickets, but please cancel your booking if you can't make it. Also consider donating to the Humanitarian OpenStreetMap Team to help us do our work.
