[Termes IGN] visualisation 3DRésumé : (Editeur) The Miage Glacier at Mont-Blanc Massif, with an area totalling 11km2 is the third largest glacier in Italy. Time-space modelling of the lakebed and glacier walls carried out with terrestrial Lidar revealed that the ice cliff had retreated more than 45m between july 2003 and september 2004.

[Termes IGN] modèle numérique de surfaceRésumé : (Auteur) This paper is concerned with the application of high spatial resolution elevation data derived from light detection and ranging technologies (lidar) to surface hydrologic modeling. In recent years, airborne lidar technology bas been employed to develop high accuracy digital elevation models (DEMs) with horizontal resolution on the order of a few meters. As with any spatial data product there are limits to the lidar's practical use that vary with the intended application. This paper considers potential issues and challenges for the use of lidar-derived DEMs in surface hydrologic modeling applications, such as characterizing flow direction and power, identifying sub-basins in a watershed, and calculating upstream contributing area and other variables. We compare results using conventional 30m DEMs and 6m lidar for a high relief study area and a low relief study area. Results are more comparable between these data sources, regardless of hydrologic operation, for the high relief area, while the similarity of results in the low relief area is dependent upon the particular operation. Post-processing on the lidar data successfully removed such flow obstacles as bridges that might have artificially impeded surface flow. An exploration of the effect of spatial resolution on results suggests that cell size is a more significant factor than production method.

[Termes IGN] temps réelRésumé : (Auteur) Geokosmos has been in practice in Russia and globally for the last few years. It has proven its usefulness for a wide range of topography and non-topography applications. The technology can be used instead of or in combination with classical photogrammetrical and geodetic methods. The main reason for using Geokosmos is to increase the productivity of topographic map making.

[Termes IGN] reconstruction 3DRésumé : (Auteur) Object reconstruction has attracted great attention from both computer vision and photogrammetry communities, and new technologies are being introduced into this research society. Lidar (Light Detection And Ranging) has become well recognized in the geomatics community since the late 1990s. Compared with traditional photogrammetry, lidar has advantages in measuring surface in terms of accuracy and density, automation, and fast delivery time. There is a large market in geo-data acquisition and object recognition for lidar technology (Baltsavias, 1999). In a general sense, lidar is a companion technology for traditional photogrammetry. The direct product that can be derived from lidar data is the DSM (Digital Surface Model), which depicts the topography of the earth's surface, including objects above the terrain. Further processing can be carried out to generate DEM (Digital Terrain Model) and object models like buildings, which is very useful information in telecommunication, city planning, flood control, and tourism. Morphology and classification are two commonly used methods in DEM generation and object reconstruction. However, these two methods are either sensitive to errors or of low accuracy. In this paper, a new method is proposed to extract ground points for DEM generation and to detect points belonging to buildings. A new method for boundary regularization is also proposed. The results show that buildings can be detected with high accuracy from lidar data.

[Termes IGN] véhicule automobileRésumé : (Auteur) Concerns about airspace security in Afghanistan literally brought a LiDAR-based survey operation down to the ground. Fashioning a truck-back system, Canadian engineers used GPS and inertial measurement to time and locate the laser-ranging "hits" that would construct a digital elevation model of the badly damaged highway. The return to an earlier prototype now affords a quick, cost-effective solution for other survey situations.
