[Termes IGN] traitement d'imageRésumé : (Auteur) The spatial variability of elevation errors in high-resolution digital elevation models (DEMs) derived from stereo-image processing is examined. Error models are developed and evaluated by examining the correlation between various DEM parameters and the magnitude of the observed DEM vertical error. DEM vertical errors were estimated using a dataset of more than 51000 points of known elevation obtained from a kinematic global positioning satellite (GPS) ground survey. Elevation variability and the quality of the stereo-correlation match over small spatial scales were the dominant factors that determined the magnitude of the DEM error at any given location. The error models are strongly correlated with the magnitude of the DEM vertical error and are shown to adequately represent the full range of the observed error. The error models are used to estimate the magnitude of the vertical error for every point in the DEMs. The models are then used to predict the overall error in the DEMs. The results demonstrate that the error models can accurately quantify and predict the spatial variability of the DEM error.

[Termes IGN] troncRésumé : (Auteur) The objective of this paper is to investigate the relationships between VHF data and forest biomass using data acquired by the Airborne Imaging Radar CARABAS over two different pine plantation forests in southern France. Data are analyzed using detailed ground truth measurements available on both sites. The backscattering coefficient is strongly correlated to characteristics of the tree trunk. Signal saturation is not observed up to 900 m' /ha. However, the sensitivity to the volume is high in the range of 0500 m' /ha (e.g., 1 to 1.5 dB for 50 m3/ha), whereas it is reduced beyond 500 m3/ha ( Numéro de notice : A2001-131 Affiliation des auteurs : non IGN Thématique : FORET/IMAGERIE Nature : Article nature-HAL : ArtAvecCL-RevueIntern DOI : 10.1109/36.964972 En ligne : https://doi.org/10.1109/36.964972 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=21827

[Termes IGN] trait de côteRésumé : (Auteur) A new method for the recognition and mapping of surfaces in coastal landscapes that provide accurate and low variability topographic measurements with respect to airborne lidar surveys is described and demonstrated in this paper. Such surfaces are herein termed "fiducial" because they can represent reference baseline morphology in studies of coastal change due to natural or anthropogenic causes. Nonfiducial surfaces may also be identified in each separate lidar survey to be used in a given geomorphic change analysis. Sites that are nonfiducial in either or both lidar surveys that bracket the time period under investigation may be excluded from consideration in subsequent calculations of survey-to-survey elevation differences to eliminate spurious indications of landscape change. This new analysis method, or lidar fiducial surface recognition (LFSR) algorithm, is intended to more fully enable the nonambiguous use of topographic lidar in a range of coastal investigations. The LFSR algorithm may be widely applied, because it is based solely on the information inherent in the USGS/NASA/NOAA airborne topographic lidar coverage that exists for most of the contiguous U.S. coastline.

[Termes IGN] visualisation 3DRésumé : (Auteur) The automation of feature extraction from digital imagery is the most challenging task facing those working today in photogrammetry research and development. Unsolved so far is the fully automatic and reliable detection and reconstruction of objects. There are solutions available for the automation of specific tasks under certain restrictions, but all methods show deficiencies when faced with poor image quality. Occlusions and shadows are factors which frequently prevent high success rates. One current practice involves a semiautomatic approach, a human operator being employed for the extremely difficult interpretation tasks. The authors present an overview of inJECT, a semiautomatic building extraction system. This system, developed by INPHO in cooperation with the Institute of Photogrammetry at the University of Bonn, offers a set of building primitives covering the most common basic house shapes. Automated modules assist the human operator in the measuring phase. The system does not require stereo viewing and operators need only a short course of training.
