This article presents two 3D historical enriched models projects; Nantes 1900 and Virtual Leodium. They are both based on mock-ups realised in the early 20th century. They share the same goal; creating participatory and evolutionary historical knowledge models, built on a 3D virtual copy of original mock-ups. Both projects are described and compared with specific highlight on methodological sim...

As our urban environments are densifying, it is essential to extend traditional cadastral systems that are based on two dimensional representation of ownership to support 3D. With the need to define property ownership in vertical as well as horizontal dimensions becoming pertinent around the world, a practical solution to represent 3D cadastral data is needed. The Land Administration Domain Mod...

The CityGML standard enables the modelling of some topological relationships, and the representation in multiple levels of detail (LODs). However, both concepts are rarely utilised in reality. In this paper we investigate the linking of corresponding geometric features across multiple representations. We describe the possible topological cases, show how to detect these relationships, and how to...

Creating as-built plans of building interiors is a challenging task. In this paper we present a semi-automatic modelling system for creating residential building interior plans and their integration with existing map data to produce building models. Taking a set of imprecise measurements made with an interactive mobile phone room mapping application, the system performs spatial adjustments in a...
