Abstract :	[en] The need of 3D urban spatial data infrastructures (3D SDI) is now almost commonly accepted. However, their implementation suffers from a lack of standardisation. This is usually due to an underestimation of the initial conceptual step, where modelling options should be clearly stated. In this article, we present a modelling ontological approach inspired by our experience in spatial data acquisition techniques. In this ontology, one considers that the universe is composed of free space and occupied space and that their interface is the only measurable feature. On that basis, we present a generic 3D urban spatial information meta-model. This meta-model is compared to the City GML standard through the study of the building object. Expect from some level-ofdetail issues, both models are compatible.
