Patrick Meier launched a volunteer network to connect responsible civilian UAV pilots who are interested in safely and legally supporting humanitarian efforts when the need arises. In the mission of the draft strategy document it says:
[The mission is to] Create a global volunteer network of responsible civilian and hobbyist UAV pilots to facilitate information sharing, coordination and operational safety in support of humanitarian efforts. The purpose of this network is to be pro-active in educating new civilians pilots rather than waiting for mistakes to be made. The mission is thus two-fold, facilitating safe operations and establishing standards for the use of UAVs in humanitarian contexts.
If you are interested in crowdsourced disaster management you should take a look at it.
