[Termes IGN] San DiegoRésumé : (Auteur) With the development of new remote sensing systems, very high spatial and spectral resolution images now provide a source for detailed and continuous sampling of the Earth's surface from local to regional scales. This paper presents three strategies for selecting and integrating information from different spatial resolutions into classification routines. One strategy is to combine layers of image varying resolution. A second strategy involves comparing the a posteriori probabilities of each class at different resolutions. Another strategy is based on a top-down approach stating with the coarsest resolution. The multiresolution strategies are tested using simulated multiresolution images for a portion of the rural-urban fringe of the SanDiego Metropolitan Area. The classification accuracy obtained from using three multiple strategies was greater when compared with that from a conventional single-resolution approach. Among the three strategies, the top-down approach resulted in the highest classification accuracy with a Kappa value of 0,648 compared to a Kappa of 0,566 for the conventional classifier.

[Termes IGN] Union EuropéenneRésumé : (Auteur) The Geographical Information & Geographical Information Systems (GI&GIS) project of the Joint Research Centre is actively involved in assisting in the creation of the European Spatial Data Infrastructure (ESDI), as well as in activities related to the conception, creation and harmonization of pan-European spatial databases relevant for the policies of the European Union (EU), mainly through the support and co-ordination of networks in various thematic fields. Remotely sensed datasets play an important role in the ESDI and it is argued that the creation of an ESDI will greatly impact the GI and the remote sensing communities alike. Hence the main objective of this paper is to make the remote sensing community familiar with the current developments at EU level. This paper also illustrates major issues related to the harmonization of existing national datasets or the creation of new ones having a European or pan-European extent. In particular, the following technical aspects are discussed : terrestrial reference systems, projection systems, core data definition and geospatial metadata.

[Termes IGN] variable aléatoireRésumé : (Auteur) As an object moves through space, it creates a track (or path) representing the object's past and present position and associated attributes. If data capture falls, then positions along the tracks are unknown. The particular problem we address in this paper is to create tracks of moving objects with missing data. We implement and test two techniques that create continuous tracks of two primate species (Ateles geoffroyi, the red spider monkey, and Cebus capucinus, the whitefaced capuchin). Continuous tracks were needed to calculate home range and to analyze daily ranging patterns for each species. Establishing continuous tracks of primates through field data alone, however, was impossible due to challenging field conditions. The results of the analysis using tracks with interpolated positions helped establish that Ateles tend to move directly to their destination while Cebus tended to follow a more wandering track.

[Termes IGN] The National Map (USA)
[Termes IGN] United States Geological SurveyRésumé : (Auteur) The National Map represents an overwhelming mission to the U.S. Geological Survey (USGS), a mission that has become even more urgent in recent months. Conceptually, The National Map is a virtually continuous database built by many participants to cover our country. This is a highly innovative vision and is founded upon the collective participation of numerous Federal, state, and local government agencies as well as private industry organizations. The National Map mission can only be accomplished through collaboration of many organizations and effective use of geographic information systems (Gis). Gis technology will serve as the foundation for The National Map by providing a framework and mechanism for many organizations to work in concert. Building The National Map depends upon the presence of a strong, open, interoperable Gis infrastructure as well as key Gis technologies and methodologies.

[Termes IGN] The National Map (USA)
[Termes IGN] United States Geological SurveyRésumé : (Auteur) When the means of production for national base mapping were capital intensive, required large production facilities, and had illdefined markets, Federal Government mapping agencies were the primary providers of the spatial data needed for economic development, environmental management, and national defense. With desktop geographic information systems now ubiquitous, source data available as a commodity from private industry, and the realization that many complex problems faced by society need far more and different kinds of spatial data for their solutions, national mapping organizations must realign their business strategies to meet growing demand and anticipate the needs of a rapidly changing geographic information environment. The National Map of the United States builds on a sound historic foundation of describing and monitoring the land surface and adds a focused effort to produce improved understanding, modeling, and prediction of landsurface change. These added dimensions bring to bear a broader spectrum of geographic science to address extant and emerging issues. Within the overarching construct of The National Map, the U.S. Geological Survey (USGS) is making a transition from data collector to guarantor of national data completeness; from producing paper maps to supporting an online, seamless, integrated database; and from simply describing the Nations landscape to linking these descriptions with increased scientific understanding. Implementing the full spectrum of geographic science addresses a myriad of public policy issues, including land and natural resource management, recreation, urban growth, human health, and emergency planning, response, and recovery. Neither these issues nor the science and technologies needed to deal with them are static. A robust research agenda is needed to understand these changes and realize The National Map vision. Initial successes have been achieved. These accomplishments demonstrate the utility of The National Map to the Nation and give confidence in evolving its future applications.
