This paper discusses approaches to identify location-dependent information for emergency managers, in order to make quick but solid decisions, and improve the coordination of activities performed by crowdsourcees during disaster response. In this regard, the idea of considering location as a driver for flexibility in the design of business processes is prepared, and the meaning of location-dependent tasks for volunteers is investigated. In terms of emergency management, the paper sheds light on what may have to be considered by emergency managers when coordinating activities performed by volunteers, followed by an illustration of how they can be aware of location-based information using crowdsourcing, as well as how visualization of this information can support decision-making.
