UNOSAT has made available a free crowd-sourcing app, called UN-ASIGN. It is a tool for taking and sharing geo-tagged photos specifically designed to work over low bandwidth. The photos are automatically mapped, thus helping towards overall situational awareness.

Individual contributors can see their own photos on Google Maps, while UNOSAT will have access to all photos and share those relevant with UN OCHA and other coordination entities. The photos appear in real time as long as the volunteer has a GSM or Internet connection.

So far, the tool has successfully been used in Haiti, Pakistan, Nigeria and Thailand, a webmap showing images collected during the Thailand floods of 2012 can be seen here:
