Study on crowdsourcing-compatible disaster information management system based on GIS

Under the development of mobile Internet and SNS, crowdsourcing has become a new method of information exchange and promoted information production and exchanging on Internet. During the processes of disaster relief, mass of information created and released by normal people have been used and played an important role. Using crowdsourcing in disaster information collection can improve the efficiency of rescue, especially when correct position is attached. Based on the analysis of current status of disaster information collection, crowdsourcing model and VGI, this paper studied the crowdsourcing-compatible disaster information management system based on GIS, including its' content, architecture, technical challenge and future development direction.
