[Termes IGN] surface de la merRésumé : (Auteur) In July 2007, a new Light Detection And Ranging (LIDAR)-based water-level measurement system was installed at the Harvest platform with the goals of assessing potential drifts in the primary National Oceanic and Atmospheric Administration (NOAA) water level (bubbler) system and of providing insight on other environmental conditions which may affect the bubbler accuracy. In addition, the LIDAR provides an independent measure of significant wave height (SWH), which has traditionally been derived from nearby buoys (operated by Scripps and NOAA). The open ocean environment of the Harvest Platform has presented significant challenges. Despite these difficult operating conditions, the LIDAR system has shown promise in being able to assess drift in the bubbler as well as the dependencies on SWH and wind speed. However, a longer time series of data and better environmental condition measurements are needed in order to make an assessment of these parameters with the desired accuracy (e.g., drift to better than 1 mm/yr).

[Termes IGN] WebSIGRésumé : (Auteur) Several announcements in recent years by the United States and Canadian governments featuring their space exploration plan have one major thing in common: mission preparation at terrestrial analogue sites. Mission simulations carried out at these sites often involve traverses that allow access to areas of special interest needed to meet mission’s objectives. Despite many recommendations, no WEB-based geographic information system exists for terrestrial analogues for mission planning. This paper reports the development of a WEB-based geographic information system for terrestrial analogues, illustrated using the example of the Haughton impact crater analogue site. This system demonstrates functionality that provides users with tools to plan their missions by enabling traverse planning between areas of interest based on a least cost path analysis method. The geographic information system will be composed of open source libraries and software, and will be compliant with Open GeoSpatial Consortium standards.

[Termes IGN] surface (géométrie)Résumé : (Auteur) As part of the ongoing activities for the European space mission BepiColombo to Mercury, a new stereo-matching algorithm is here proposed: this algorithm uses deformable surfaces, or snakes, to find a dense disparity map. Subject to both external and internal forces, respectively represented by the similarity function and by smoothness constraints on the disparity map, a "deformable" disparity map evolves from an initial approximate state to an optimal one in which the algorithm has reached convergence. This algorithm is expected to provide one of the image matching tools for the Digital Terrain Model generation procedure that will be used by the BepiColombo stereo camera. To check the algorithm, tests have been performed on synthetic images derived from 3D models of geological features relevant to planetary science. The results show that it is possible to obtain an image measurement accuracy comparable to the one attainable with the Least Squares Matching algorithm. In addition, less object smoothing can be obtained since the object points are not derived by a large scale averaging over a terrain patch, as for example, in area-based methods; this means that more details of the terrain can be captured. Finally, because of the continuity constraint, this method is also expected to be robust in case of blunders in the reconstruction of the parallax field.

[Termes IGN] SCAN25Résumé : (Auteur) Les bases de données d'occupation du sol à l'échelle régionale remportent un vif succès, comme l'a montré la journée organisée sur le sujet par le CRIGE PACA et SIG-LR le 7 décembre dernier. Malgré une popularité croissante, les utilisateurs reconnaissent également avoir besoin de données à échelles plus précises. Parallèlement, les programmes européens (GMES, INSPIRE, Corine Land Cover...) et nationaux visent à produire des bases nationales. Comment assurer la cohérence entre ces nombreuses productions? La question est loin d'être réglée.

[Termes IGN] surveillanceRésumé : (Auteur) There is an increasing need for Earth Observation (EO) missions to meet the information requirements in connection with Global Change Studies. Small and cost-effective missions are powerful tools to flexibly react to information requirements with space-borne solutions. Small satellite missions can be conducted relatively quickly and inexpensively by using commercial off-the-shelf-technologies, or they can be enhanced by using advanced technologies. A new class of advanced small satellites, including autonomously operating “intelligent” satellites may be created, opening new fields of application. The increasing number of small satellites and their applications drive developments in the fields of small launchers, small ground station networks, cost-effective data distribution methods, and cost-effective management and quality assurance procedures. There are many advantages of small satellite missions, like more frequent mission opportunities, a faster return of data, larger variety of missions, more rapid expansion of the technical and/or scientific knowledge base, greater involvement of small industry, feasibility by universities and others. $This paper deals with general trends in the field of small satellite missions for Earth observation. Special attention is given to the potential of spatial, spectral, and temporal resolution of small satellite based systems. Examples show small satellites offer also the unique possibility to install affordable constellations to provide good daily coverage of the globe and/or allow us to observe dynamic phenomena. The facts and examples given in this paper lead to the conclusion: Small satellites are already powerful tools for monitoring global, regional and local phenomena. In the future, their application spectrum will even broaden based on the ongoing development in many areas of technology and observation techniques.
