1 Ontologies for the Integration of Air Quality Models and 3D City Models Claudine Metral Institut d’architecture - University of Geneva Site de Battelle - 7, route de Drize - CH 1227 Carouge/Geneva - Switzerland [email protected] Gilles Falquet Department of Information Systems - University of Geneva Site de Battelle - 7, route de Drize - CH 1227 Carouge/Geneva - Switzerland [email protected] Kostas Karatzas, Informatics Applications and Systems Group, Dept. of Mechanical Engineering Aristotle University, GR-54124 Thessaloniki, Greece [email protected] Abstract In the perspective of a sustainable urban planning, it is necessary to investigate cities in a holistic way and to accept surprises in the response of urban environments to a particular set of strategies. For example, the process of inner-city densification may limit air pollution, carbon emissions, and energy use through reduced transportation; on the other hand, the resulting street canyons could lead to local levels of pollution that could be higher than in a low-density urban setting. The holistic approach to sustainable urban planning implies using different models in an integrated way that is capable of simulating the urban system. As the interconnection of such models is not a trivial task, one of the key elements that may be applied is the description of the urban geometric properties in an “interoperable” way. Focusing on air quality as one of the most pronounced urban problems, the geometric aspects of a city may be described by objects such as those defined in CityGML, so that an appropriate air quality model can be applied for estimating the quality of the urban air on the basis of atmospheric flow and chemistry equations. It is generally admitted that an ontology-based approach can provide a generic and robust way to interconnect different models. However, a direct approach, that consists in establishing correspondences between concepts, is not sufficient in the present situation. One has to take into account, among other things, the computations involved in the correspondences between concepts. In this paper we first present theoretical background and motivations for the interconnection of 3D city models and other models related to sustainable development and urban planning. Then we present a practical experiment based on the interconnection of CityGML with an air quality model. Our approach is based on the creation of an ontology of air quality models and on the extension of an ontology of urban planning process (OUPP) that acts as an ontology mediator.

2 1. Introduction Sustainable development and urban planning One of the most often cited definitions of sustainability is the one created by the Brundtland Commission in its report (Brundtland, 1987) which defined sustainable development as development that "meets the needs of the present without compromising the ability of future generations to meet their own needs." The report

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
