Special issue of Data Engineering: “Most data related to people and the built world originates in urban settings. There is increasing demand to capture and exploit this data to support efforts in areas such as Smart Cities, City Science and Intelligent Transportation Systems. Urban informatics deals with the collection, organization, dissemination and analysis of urban information used in such applications. However, the dramatic growth in the volume of this urban data creates challenges for existing data-management and analysis techniques. The collected data is also increasingly diverse, with a wide variety of sensor, GIS, imagery and graph data arising in cities. To address these challenges, urban informatics requires development of advanced data-management approaches, analysis methods, and visualization techniques. It also provides an opportunity to confront the “Variety” axis of Big Data head on. The contributions in this issue cross the spectrum of urban information, from its origin, to archiving and retrieval, to analysis and visualization. …
