This paper presents the design and implementation of a new generation platform for the smart city ecosystem that offers valuable information on multiple urban dimensions, and whose knowledge provides a direct impact on a large spectrum of users with different interests. This platform will provide a powerful monitoring and control infrastructure that will enable planners to make critical management decisions both on tactical and strategic levels based on the knowledge acquired from the platform software components. This chapter describes such a component called Citizen Incident Reporting, which is a software module that allows citizens to effectively participate in the local governance by documenting their concerns and sending reports to the government order management services. As such, the mobile application will provide better communication between citizens that can spot problems and authorities responsible for their resolution within the Smart City ecosystem.
