In pictures: Mapping in action

		Knowledge distribution MapAction volunteers work with aid agencies as well as locals on the ground, gathering and distributing location-based data as it is needed. "It becomes a two-way street; the people who are acquiring information from us are often the people from whom information can be gathered.” One of the most important map types is a "Who What Where" map showing which relief agencies are doing what work in which area. From this, Mr Woof says, it becomes clear where the gaps are in the response.
