Table 8 The key functions of horizontal information systems

• Providing open platforms connecting all the sensors installed in the city and the obtained sensed data Aggregating and standardizing the flows of functional and territorial data from municipal sources, the systems of state control (mobility, energy, noise level, pollution level, etc.), business environment, and other state agencies (hospitals, cultural institutions, universities, schools, etc.), as well as from various detectors and cameras for their subsequent integrated analysis and visualization in 3D format

• Solving the problems of data disconnection in the city through the open operating system integrating and processing the information generated by the city

• Reworking and repackaging the collected data for daily consumption by different stakeholders

• Allowing the city authorities and third party users to gain access to the received data in a more structured and convenient manner for software development

• Providing comprehensive solutions to complex urban problems by integrating the self-contained and unconnected technological solutions and information systems used in the different functional departments of the city

• Improving the efficiency and performance of implemented applied technological solutions

• Allowing the city authorities and other users to take decisions on the optimization of the city activities in the short, medium, and long term
