Can satellite imagery and UAV data become useful data sources for humanitarian decision making in disaster relief coordination?

Satellite Imagery and data collected by unmanned aerial vehicles (UAVs) are increasingly promoted as valuable new information sources to aid humanitarian emergency decision making, but how much have things really changed? MapAction is at the forefront of information management delivery on the ground in humanitarian relief, and the choice of which data we use depends on what is best for how to get aid to affected people. Our primary aim is to inform decision making by mapping for people in a crisis, ensuring the best data is timely in delivery to help those affected. Do satellite imagery or data from unmanned aerial vehicles or UAVs make a difference in the field yet? We consider the evidence from our perspective.
