Whereas simple 3D city models of the exterior of buildings (e.g. CityGML LOD2) can be generated largely automatically, and are thus now widely available and have a great variety of applications, similarly simple models containing their indoor geometries are rare.
In this paper we present two contributions: (i) the definition of a level of detail LOD2+, which extends the CityGML LOD2 specification with indoor building geometries of comparable complexity to their exterior geometries in LOD2; and more importantly (ii) a method for automatically generating such indoor geometries based on existing CityGML LOD2 exterior geometries. We validate our method by generating LOD2+ models for a subset of the Rotterdam 3D data set and visually comparing these models to their real counterparts in building blueprints and imagery from Google Street View and Bing Maps. Furthermore, we use the LOD2+ models to compute the net internal area of each dwelling and validate our results by comparing these values to the ones registered in official government data sets.Numéro de notice : A2015-624 Affiliation des auteurs : non IGN Thématique : GEOMATIQUE Nature : Article nature-HAL : ArtAvecCL-RevueIntern DOI : 10.1080/13658816.2015.1072201 En ligne : https://doi.org/10.1080/13658816.2015.1072201 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=78093

[Vedettes matières IGN] GéovisualisationRésumé : (auteur) With the rapid urbanisation and development of three-dimensional (3D) space use, space objects in residential houses are of increasing concern. Illustrating these spatial entities within a clustered and multi-layered environment is confronted with the long-standing cognitive challenges of visual occlusion, visual clutter and visual navigation. Direct illustration as cross sections and cutaways provide valuable instruction for removing occlusion while preserving global contexts to give positioning cues. However, cross-sectioning or cutting away of the popular boundary-described models suffers from computational robustness and efficiency problems, while separated boundary geometry with surface properties prevents the efficient image-based direct illustrations from implementing a visually complete, semantically consistent practice easily. This article proposes a semantic volume texture (SVT) model for direct illustration. This true-3D raster model integrates spatial pattern embedding as well, thus avoiding the costly amendments to keep semantic consistent and visually complete during illustrative cutting and reconstructing operations. The proposed model is extended to the practical base of CityGML schema, the preparation of SVT is presented and applications imitating cross sections and cutaways are demonstrated. Experiments show that SVT-based direct illustrations are effective and efficient, making the proposed model suitable for explorative visualisations in the layered micro-scale environments.

[Termes IGN] Web View ServiceRésumé : (Auteur) Land has an essential role in any society, either as one of the most important capitals of mankind or as a place for people's life and activities. Therefore, registration of ownership and land use rights in a formal system is a major issue. In different countries, Cadastre systems can register extent, rights, restrictions and responsibilities related to land parcels. Many organizations such as municipality, tax and banks need to this information for planning and decision making. Considering the needs for land information by different organizations, access to cadastre data gains a lot of importance. Despite this importance, access to cadastre information encounter with different challenges such as differences in platforms or data structures and access to semantic and geometric data. The main goal of this research is to overcome these challenges and to improve the interoperability in sharing and accessing 3D cadastre data and challenges. This paper investigates capabilities of current 3D Spatial Web Services: WFS, WVS, WTS and W3DS as well as advantages of using these 3D services for access to 3D cadastre data. The authors also combined the legal classes of LADM with geometrical classes of CityGML for transferring the semantic and geometric cadastre data. Finally, some prospects of using 3D Web Services will be illustrated through implementation the scenarios. The most important advantages of using 3D Spatial Web Services in cadastre are on the fly construction and on demand presentation of 3D cadastral model, facilitating of access to legal and descriptive cadastre information, no necessity to user's awareness of data structure in cadastre database and compatibility with different levels of users.

Defining 3D GIS city models in different levels of detail (LoD) is often needed to browse and handle large models more efficiently. In this paper, a methodology framework for automatic transformation of different LoDs in CityGML is presented and illustrated. A new exterior shell extraction algorithm was developed from the Ray Tracing algorithm for classifying building surfaces as interior or exterior. A transformation framework among each LoD was developed based on the new exterior shell extraction algorithm. The transformation framework also includes an additional LoD called LoD3.5 that the authors proposed in this paper. The new LoD can satisfy the needs of applications which require information about interior rooms while maintaining a small data storage. The results show that the new exterior shell extraction algorithm can help achieve an automatic derivation of LoDs in CityGML.
