The main objective of the action is to semantically enrich 3D models with urban knowledge and models, so as to extend their functionality and usability in a perspective of sustainability.

3D city models

A 3D city model is a three dimensional digital representation of a city or urban environment, using data derived from multiple sources such as stereo aerial images, airborne Lidar data and high resolution satellite data. It contains a large number of objects of different classes and different data models and structures.
It is an important tool used in various fields such as urban planning and management, facility location, or car-navigation systems, as well as for research and 3D visual representation of the urban environment as textured images or fly-throughs.
CityGML is an information model for the representation of 3D urban objects. It defines the classes and relations for the objects with respect to their geometrical, topological, semantical, and appearance properties.

Sustainable development

Sustainable development of cities implies investigating cities in a holistic way taking into account many interrelations between various urban or environmental issues, such as spatial planning, traffic and transport, energy, air quality, health, risks, and cultural heritage.
