Urban information dashboards using three-dimensional model and open data

Abstract

In urban areas, 3D city models and open data are publicly available. However, these datasets lack uniformity in data formats and management methods, making unified visualization challenging. Furthermore, existing urban information dashboards are specialized for specific regions or purposes, making it difficult to apply them to other cities or tailor them to user interests. This research developed a universal urban information dashboard that supports understanding a city's current state by enabling unified 3D visualization of diverse urban data, independent of specific regions. To achieve this, we created an environment that processes geospatial data, hazard data, and statistical data according to their respective types and visualizes them centrally on a single dashboard. We visualized multiple sets of urban data on the developed dashboard, demonstrating its versatility, usability, and scalability.
