Urban data ranges from geospatial data for environment and construction to geometry data of buildings and information from the Internet of Things. How can a city's heterogeneous data sets be made available in a uniform manner via open interfaces and standards? Previous communication networks for data transmission are currently being expanded by new radio technologies such as 5G. What potential do these technologies have for use in buildings and cities? The increasing volume of data also requires automated processing to make the data valuable. How can new methods such as deep learning contribute to this? Finally yet importantly, how can data collected in the city and its buildings contribute to a better use of public resources, for example via new services for citizens?
