Visualization Technologies to Support Decision-Making in City Management

Data is a valuable asset to the management of a city. With the growing integration of technology, some tools help collect, process, and visualize urban data, aiding the interpretation and understanding of how urban systems work. Despite the wide use of visualization to support decision-making in urban management, the understanding of urban data visualization in cities is limited in the current literature. In this paper, we propose a model of human decision-making supported by Information and Communication Technologies that helps understand the role of urban data visualization in city management. To analyze the use of visualization technologies in city management, we review the advances of information visualization to support decision-making in city management, and present a field study where we surveyed 35 government institutions to explore urban data and technologies "real use" in city management. Based on the literature review results and the field study, we identified the areas of opportunity for visualizing urban data to support city management.
