[Termes IGN] relation topologiqueRésumé : (Auteur) While CityGML permits us to represent 3D city models, its use for applications where spatial analysis and/or real-time modifications are required is limited since at this moment the possibility to store topological relationships between the elements is rather limited and often not exploited. We present in this paper a new topological data structure, the dual half-edge (DHE), which permits us to represent the topology of 3D buildings (including their interiors) and of the surrounding terrain. It is based on the idea of simultaneously storing a graph in 3D space and its dual graph, and to link the two. We propose Euler-type operators for incrementally constructing 3D models (for adding individual edges, faces and volumes to the model while updating the dual structure simultaneously), and we also propose navigation operators to move from a given point to all the connected planes or polyhedra for example. The DHE also permits us to store attributes to any element. We have implemented the DHE and have tested it with different CityGML models. Our technique allows us to handle important query-types, for example finding the nearest exterior exit to a given room, as in disaster management planning. As the structure is locally modifiable the model may be adapted whenever a particular pathway is no longer available. The proposed DHE structure adds significant analytic value to the increasingly popular CityGML model.

In 2000, the unmapped areas at a scale of 1:50,000 in the Arctic islands in Nunavut and the Northwest Territories, amount to over 800,000 square kilometres, equivalent to approximately 1,500 map sheets. In 2003, a northern mapping project was launched to complete the topographic map coverage in Northern Canada. In order to explore all possible scenarios, the Centre for Topographic Information – Sherbrooke (CTIS) worked closely with the Canadian Space Agency and the private sector on various feasibility tests. After investigating multiple data sources, the combination of existing aerial photography, LANDSAT 7 ETM+, SPOT5/HRS imagery, interferometric pairs of ERS 1-2 tandem and RADARSAT-2 imagery were chosen for planimetric data and Canadian Digital Elevation Data (CDED) acquisition. In 2004, mapping contracts were carried out on a test site and positive results from these tests initiated the production of the unmapped areas of Canada. The planimetric vector data are available on the GeoGratis Web portal and the CDED data sets are available on the GeoBase Web portal.

[Termes IGN] reconstruction 3D du bâtiRésumé : (Auteur) This paper presents a method to assess the geometric quality of 3D building models. The quality depends on properties of the input data and the processing steps. Insight in the quality of 3D models is important for users to judge whether the models can be used in their specific applications. Without a proper quality description it is likely that the building models are either treated as correct or considered as useless because the quality is unknown. In our research we analyse how the quality parameters of the input data affect the quality of the 3D models. The 3D models have been reconstructed from dense airborne laser scanner data of about 20 pts/m2. A target based graph matching approach has been used to relate specific data features to general building knowledge. The paper presents a theoretical and an empirical approach to identify strong parts and shortcomings in 3D building models reconstructed from airborne laser scanning data without the use of reference measurements. Our method is tested on three different scenes to show that a proper quality description is essential to correctly judge the quality of the models.

[Termes IGN] orthoimage intégraleRésumé : (Auteur) In cooperation with Diamond Airborne Sensing, the Tiltan company has developed a highly integrated airborne image data acquisition and photogrammetric processing system. This utilizes digital frame images that have been acquired employing the step framing principle in a convergent oblique mode to produce its stereo-coverage of the terrain. The overlapping stereo-images can then be used to produce true orthophotos and 3D urban models using highly automated photogrammetric image processing techniques.
