City Models

Many urban or environmental models are defined with the objective of helping practitioners and stakeholders in their decision-making processes. Models which represent in three dimensions the geometric elements of a city are called 3D city models. These models are increasingly used in different cities and countries for an intended wide range of applications beyond mere visualisation. Indeed, unlike maps and drawings, 3D visualisation reflects a view of the environment that a lot of people are familiar with and acts as a communication tool. Non geometrical data (such as social, historic or acoustic data or statistics, for example) can be associated to urban geometrical objects (such as buildings or streets) that can be represented and visualized in 3D, leading to a localization as well as a better understanding of these data. By associating a domain (energy consumption, air quality, etc.) to these 3D models, we obtain richer 3D representations that can be used for simulations and reasoning (visual reasoning).
