[Termes descripteurs IGN] valeur discrèteRésumé : (Auteur) Geoscientific datasets are often formed by scattered samples in 3D space having highly anisotropic distribution. To model the continuity of the phenomena they represent (e.g. temperature of a body of water, or percentage of a chemical in the air) raster structures are in most cases used. To overcome the shortcomings of rasters the Voronoi diagram (VD) has been proposed as an alternative. However, while in theory the VD is a sound solution, its use in practice is hindered by the fact that it is complex to construct and to manipulate (removal of samples, interpolation, etc.), and spatial tools have to be built. We propose in this paper a “middle" solution: the 3D discrete Voronoi diagram (DVD). We investigate the properties of the 3D DVD, we propose algorithms to construct and manipulate it, and we demonstrate its use in practice with a prototype that we have built. Our prototype uses existing tools for visualisation and further analysis of DVDs.

In recent years, research has focused on improving 3D data acquisition technology through remote sensing, photogrammetry, laser altimetry techniques (LiDAR), and visualization technology (3D CAD and Virtual Reality (VR) system) for 3D urban environments. The resulting 3D models can be maintained in several types of 3D models: TEN (Tetrahedral Network), Constructive Solid Geometry (CSG) models, Regular Polytopes, TIN Boundary representation and 3D volume quad edge structure, layered/topology models, voxel based models, 3D models used in urban planning/polyhedrons, and n-dimensional models including time. However, researchers still face many challenges today regarding the development of suitable data models representing topological relationships among 3D spatial objects in built environments.

[Termes descripteurs IGN] modélisation 3D du bâti BIMRésumé : (Auteur) 3D City models have so far neglected utility networks in built environments, both interior and exterior. Many urban applications, e.g. emergency response or maintenance operations, are looking for such an integration of interior and exterior utility. Interior utility is usually created and maintained using Building Information Model (BIM) systems, while exterior utility is stored, managed and analyzed using GIS. Researchers have suggested that the best approach for BIM/GIS integration is harmonized semantics, which allow formal mapping between the BIM and real world GIS. This paper provides preliminary ideas and directions for how to acquire information from BIM/Industry Foundation Class (IFC) and map it to CityGML utility network Application Domain Extension (ADE). The investigation points out that, in most cases, there is a direct one-to-one mapping between IFC schema and UtilityNetworkADE schema, and only in one case there is one-to-many mapping; related to logical connectivity since there is no exact concept to represent the case in UtilityNetworkADE. Many examples are shown of partial IFC files and their possible translation in order to be represented in UtilityNetworkADE classes.
