[Termes IGN] SIG 3DRésumé : (auteur) The level of detail (LOD) of a 3D city model indicates the model’s grade and usability. However, there exist multiple valid variants of each LOD. As a consequence, the LOD concept is inconclusive as an instruction for the acquisition of 3D city models. For instance, the top surface of an LOD1 block model may be modelled at the eaves of a building or at its ridge height. Such variants, which we term geometric references, are often overlooked and are usually not documented in the metadata. Furthermore, the influence of a particular geometric reference on the performance of a spatial analysis is not known.
In response to this research gap, we investigate a variety of LOD1 and LOD2 geometric references that are commonly employed, and perform numerical experiments to investigate their relative difference when used as input for different spatial analyses. We consider three use cases (estimation of the area of the building envelope, building volume, and shadows cast by buildings), and compute the deviations in a Monte Carlo simulation.
The experiments, carried out with procedurally generated models, indicate that two 3D models representing the same building at the same LOD, but modelled according to different geometric references, may yield substantially different results when used in a spatial analysis. The outcome of our experiments also suggests that the geometric reference may have a bigger influence than the LOD, since an LOD1 with a specific geometric reference may yield a more accurate result than when using LOD2 models.Numéro de notice : A2016-577 Affiliation des auteurs : non IGN Thématique : GEOMATIQUE Nature : Article nature-HAL : ArtAvecCL-RevueIntern DOI : 10.1016/j.isprsjprs.2016.03.003 En ligne : https://doi.org/10.1016/j.isprsjprs.2016.03.003 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=81709

[Termes IGN] visualisation 3DRésumé : (auteur) In 2014 the surveying and mapping administration of North Rhine-Westphalia (Geobasis NRW, located at the Cologne Government Regional Office) provided, for the first time, a statewide national 3D-building model in the level of detail 2 (LoD2: integrated standardized roof forms). It consists of 10 million buildings. The whole derivation process was fully automatized using available reference data of the cadastre and airborne laser scan measurements.
After this first derivation of the 3D-building model, additional tasks are necessary to handle existing errors. Buildings are interactively corrected by the use of oriented aerial pictures. These changes are stored in the data base of the 3D-building model.Numéro de notice : A2016-622 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Article DOI : sans En ligne : http://dx.doi.org/10.12902/zfv-0123-2016 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=81818

[Termes IGN] spécification de produitRésumé : (auteur) The federal governments of Germany endeavour to create a harmonized 3D building data set based on a common application schema (the AdV-CityGML-Profile). In a joint research project, the Bavarian Agency for Digitisation, High-Speed Internet and Surveying and the TUM, Chair of Geoinformatics, transformed an AdV-CityGML-Profile based test data set of Bavarian LoD2 building models into an INSPIRE-compliant schema. For the purpose of a transformation of such kind, the AdV provides the data specification, a test plan for 3D building models and a mapping table. The research project examined whether the transformation rules defined in the mapping table were unambiguous and sufficient for implementing a transformation of LoD2 data based on the AdV-CityGML-Profile into the INSPIRE schema. The proof of concept was carried out by transforming production data of the Bavarian 3D building model in LoD2 into the INSPIRE BU schema. In order to assure the quality of the data to be transformed the test specifications according to the test plan for 3D building models of the AdV were carried out. The AdV mapping table was checked for completeness and correctness and amendments were made accordingly.

[Termes IGN] reconstruction 3D du bâtiRésumé : (Auteur) The international standard CityGML defines five levels of detail (LODs) for 3D city models, but only the highest of these (LOD4) supports modelling the indoor geometry of a building, which must be acquired in correspondingly high detail and therefore at a high cost. 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
