Mapathon

HP partnered with MSF, The Red Cross and Missing Maps today to put on a mapathon. 
It is aimed at helping these organisations with their crisis management by mapping previously unmapped areas to enable them to find people that need help more quickly.
It was quite a fiddly at first but surprisingly addictive and of course very worth while.
