The definition of a 3D Reference model is the prerequisite for increasing data interoperability and facing regional, national and international challenges around geographic information. Such action requires investigation of 3D user requirements and a collaborative framework to reach a consensus on common 3D data specifications. The paper presents premise reflexions about relevant issues to shape efforts towards a methodological and generic approach for dealing with a collaborative 3D reference model as a fundamental building block of 3D GIS collaborative solution. As a pilot project, we demonstrate, through a case study of the Liege city in Belgium, how data collected from different providers in Walloon region can be reengineered and then integrated in a 3D collaborative interoperable database compatible with CityGML.
