Description
Crowdsourcing has been a popular crisis mapping tool. Used to map a wide range of issues, crowdsourcing makes it easier for a large group of people from all over a region, city, country, etc., to document where problems are occurring and when. This information is used to help respond to problems, provide aid to regions that need it and keep the public up-to-date on issues as they progress.
Many thanks for this post and for highlighting an Ignite Talk from the International Conference of Crisis Mappers (ICCM 2011). In the crisis mapping space, we refer to crowdsourcing as a methodology rather than a tool.
