GIS Day - Ashcloud Apocalypse

World GIS Day was this week, and my school took part.
We participated in the Ashcloud Apocalypse event, which was organised by Raphael Heath, who won an ESRI award for his work last year.

The students used a range of web maps and a web form to enter some data.

It's not too late to enter your data to get involved and see if we can break a world record for student involvement.
