Abstract

In the context of city models, explicit semantics in terms of spatial relations and spatial properties play a crucial role for many applications and use cases. 3D models offer new opportunities (but also new challenges) to manage spatial relations and properties in city models. The work presented in this paper aims at proposing an extension of CityGML to increase its semantic expressiveness with respect to spatial relations. We first review existing relevant spatial properties and relations in city models and then analyse how to formally represent them and draft a proposed extension of CityGML.
