Grounded on archaeological information modeling works undertaken at the Geomatics Unit of the University of Liege, this paper goes a step further in handling time and function imperfection, interpretative sequences and people interacting with historical objects. Designed in 2011, the initial model already gathered both geometrical and historical information. It was partially based on the urban data standard City GML mainly for interoperability purposes. Its specificity, the version concept, allowed multiple geometries experiments. That property enabled us to handle geometrical ambiguity and incompleteness. To validate this model, and in a showcase purpose, a first prototype has been realized. One year later this prototype’s model has been improved to manage in a better way all objects’ versions and possible representations. Until now, this model integrates and manages imperfect archaeological data but only partially: the version concept being only dedicated to express geometric ambiguity or imprecision. Henceforth, with the version notion widening, we propose to encompass function and time imperfection as well. It is an important progress because on an archaeological point of view, time and function are quite generally incomplete, uncertain, imprecise or contradictory. Another enhancement must be highlighted: the agent enlistment. Historical characters, on one hand, and contemporaneous people (like authors, archaeologists etc.) on another hand are key elements of archaeological game pieces. Finally, we will describe the way of structuring versions into interpretative sequences. With those improvements, we wish to carry on feeding the scientific debate as much as drafting Archaeological Information Systems. [less ▲]

Considering sustainable development of cities implies investigating cities in a holistic way taking into account many interrelations between various urban or environmental issues. 3D city models are increasingly used in different cities and countries for an intended wide range of applications beyond mere visualization. Could these 3D City models be used to integrate urban and environmental knowledge? How could they be improved to fulfill such role? We believe that enriching the semantics of current 3D city models, would extend their functionality and usability; therefore, they could serve as integration platforms of the knowledge related to urban and environmental issues allowing a huge and significant improvement of city sustainable management and development. But which elements need to be added to 3D city models? What are the most efficient ways to realize such improvement / enrichment? How to evaluate the usability of these improved 3D city models? These were the questions tackled by the COST Action TU0801” Semantic enrichment of 3D city models for sustainable urban development”. This book gathers various materials developed all along the four year of the Action and the significant breakthroughs. [less ▲]

There are an increasing number of mobile applications supporting specific activities related to the indoor building environment. SpatioData is a research project aiming at the development of a collaborative platform for the effective sharing of building-related data and supporting a wide range of different activities. After presenting the initial requirements of the system, this paper provides a review of the standards for the building modeling and the commercial solutions currently available. Then, it describes the SpatioData building model, as well as the general system architecture. [less ▲]

Segmentation is an essential step in the production chain of point-cloud processing. It defines the pertinence and accuracy of a future 3D model reconstruction, as well as a high level analysis of any scene. Its goal is to extract from a large 3D dataset different groups of points that share a logical link to wisely consider them as one entity. Manual segmentation of a 3D point cloud is extremely time consuming and imprecise for large datasets, and thus automated classification is the main focus of this paper. [less ▲]
