[Termes IGN] visualisation dynamiqueRésumé : (Auteur) Over the recent years, spatial data have become more accessible to members of the public, and there is an increased awareness that spatial data are an essential ingredient in the development of governance policies. In parallel, computing devices that can render real-time 3D environments in nearly photo-realistic quality have become a common household item. Integrating spatial data and virtual environments opens the possibility of presenting spatial data in a highly visual way—the same way we experience our everyday world. We have developed a landscape planning tool called SIEVE (Spatial Information and Visualization Environment), which allows users to explore existing spatial data and hypothetical future scenarios in a real-time 3D environment, links to environmental process models outcomes, and also provides a collaborative decision-making environment. SIEVE has an automatic model-building component that allows users to select a region on a 2D map using a web portal and to download automatically generated 3D landscape environments. SIEVE not only models above-ground features but also incorporates underground features. This allows users to see the connection between below- and above-ground processes. Lastly, SIEVE incorporates a multi-user environment that allows users from different locations to gather in the virtual landscapes for exploring and decision-making purposes.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) The integration of geographic information systems (GIS) and spatio-temporal modeling procedures with Internet technology can significantly improve the decision-making process for environmental and disaster management. The objective of this study is to develop an approach to integrate a cellular automata (CA) forest fire behavior model with the world wide web. The developed CA model extends the capability of the static raster GIS by incorporating spatial dynamics into the forest fire phenomena. The developed CA model comprises topographic, forest fuel and weather variables as the key drivers of forest fires. The web-based modeling environment used ASP.NET as the server-side platform, and client-side programming with JavaScript extended the functionality of the web client. The web-based CA model and its consistent user-friendly interface will provide fire managers with a decision support and rapid disaster management tool with such advantages as access to real-time geospatial and environmental data, computer platform independence, and enhanced accessibility of spatial modeling tools.

[Termes IGN] toponymeRésumé : (Auteur) Natural language processing (NLP) techniques, such as toponym detection and resolution, are an integral part of most geographic information retrieval (GIR) architectures. Without these components, synonym detection, ambiguity resolution and accurate toponym expansion would not be possible. However, there are many important factors affecting the success of an NLP approach to GIR, including toponym detection errors, toponym resolution errors and query overloading. The aim of this paper is to determine how severe these errors are in state-of-the-art systems, and to what extent they affect GIR performance. We show that a careful choice of weighting schemes in the IR engine can minimize the negative impact of these errors on GIR accuracy. We provide empirical evidence from the GeoCLEF 2005 and 2006 datasets to support our observations.

[Termes IGN] visualisation 3DRésumé : (Auteur) One year after the release of Google Earth Esri announced an alternative virtual globe. The current version of ArcGIS Explorer will be evaluated here. A distinctive focus is given to different aspects such as data integrity, OGC conformity, GIS analysis capabilities, user interface and the underlying business model will have a distinctive focus. Only ArcGIS Explorer is reviewed, but compares capabilities/shortcomings to alternative virtual globes if necessary.

[Termes IGN] toponymeRésumé : (Auteur) Nowadays, a huge quantity of information is stored in digital format. A great portion of this information is constituted by textual and unstructured documents, where geographical references are usually given by means of place names. A common problem with textual information retrieval is represented by polysemous words, that is, words can have more than one sense. This problem is present also in the geographical domain: place names may refer to different locations in the world. In this paper we investigate the use of our word sense disambiguation technique in the geographical domain, with the aim of resolving ambiguous place names. Our technique is based on WordNet conceptual density. Due to the lack of a reference corpus tagged with WordNet senses, we carried out the experiments over a set of 1,210 place names extracted from the SemCor corpus that we named GeoSemCor and made publicly available. We compared our method with the most-frequent baseline and the enhanced-Lesk method, which previously has not been tested in large contexts. The results show that a better precision can be achieved by using a small context (phrase level), whereas a greater coverage can be obtained by using large contexts (document level). The proposed method should be tested with other corpora, due to the fact that our experiments evidenced the excessive bias towards the most-frequent sense of the GeoSemCor.
