[Termes IGN] représentation multipleRésumé : (Auteur) The growing awareness of the importance of spatial information has led to a continuously increasing demand for geospatial data. Thus, a lot of different companies and institutions have evolved that are aiming at satisfying this demand by capturing the real world according to the needs of different applications. This process involves that one and the same real world object is stored in several representations in different geospatial databases. The integration of these representations is a major research challenge in the field of GIS. In our approach we use a semi-automatic matching tool for defining relations between representations on the instance level. These relations are used in order to automatically derive an integrated data schema. The relations on the instance level as well as the integrated data schema can be used for automatically merging data sets, for automatically transferring updates from one data set into another or for a common analysis of spatial data from different sources.

[Termes IGN] unification des donnéesRésumé : (Auteur) As the place of change increases and new technologies emerge faster than we can assimilate them, we can be forgiven for occasionally feeling left breathless, with new technologies, new skills and new approaches required at regular intervals. In the geographic information industry new ways of collecting data, new data providers and new users entering the indusry, different ways of publishing maps and information, greater flexibility and ways of reaching all kinds of new users are all examples where the boundaries have been pushed back more in the last ten years than in the previous 100. Changes in the mainstream unferliying computing technology have enabled and facilitated this so much so more than radical new methods from within the industry. The impact of change on mapping and geographic information is great as much as any other industry or the change we witness in our own lives from day to day. However, when we stand back and consider what our overall goals are, better management of resources, better education, heath and quality of life, greater care in the use of environment etc. - these are much the same as they always have been. The difference today is that the technology now allows us to really start to address the key issues we have before us. How do we bring coherence to an apparently disconnected world ? How do we prevent difussion and potential chaos, especially when information integration is a critical success factor ? How do we organize ourselves to do that ? The paper will describe the concept of the Digital National Framework how this is now developing to support such an infrastructure and how new technologies e.g. GML are facilitating its development. The paper proposes that we have to start by simplifying the GI infrastruture and recognize the building blocks in the developing that infrastructure. We need to incorporate methods that unite and integrate difinitive information. This turn can be used to underpin all kinds of information in a joint-up way. Thereon it will support data sharing, decision making and problem-solving faster and more cost effectively than ever before.

[Termes IGN] visualisationRésumé : (Auteur) In this study, we propose, describe, and demonstrate a new geovisualization tool to demonstrate the use of exploratory and interactive visualization techniques for a visual fuzzy classification of remotely sensed imagery. The proposed tool uses dynamically linked views, consisting of an image display, a parallel coordinate plot, a 3D feature space plot, and a classified map with an uncertainty map. It allows a geoscientist to interact with the parameters of a fuzzy classification algorithm by visually adjusting fuzzy membership functions and fuzzy transition zones of land-cover classes. The purpose of this tool is to improve insight into fuzzy classification of remotely sensed imagery and related uncertainty. We tested our tool with a visual fuzzy land-cover classification of a Landsat 7 ETM + image of an area ln southern France characterized by objects with indeterminate boundaries. Good results were obtained with the visual classifier. Additionally, a focus-group user test of the tool showed that insight into a fuzzy classification algorithm and classification uncertainty improved considerably.

[Termes IGN] traitement interactifRésumé : (Auteur) High-resolution imagery is now routinely utilized to acquire geometric and attribute data for road networks. Frequently, these data must be integrated with data from other sources to meet application requirements. A critical first step in this process at data integration is to identify the correspondences between networks, so that data can be merged or transferred from one network to another. This paper introduces a semiautomated method that combines an automated algorithm and an interactive procedure to match networks that are represented differently. The automated algorithm establishes robust correspondences for nodes edges, and segments between two networks using a cluster-based matching mechanism. The interactive procedure allows a user to visually check and correct correspondences that are mismatched by the automated algorithm. Two matching examples are presented in the paper to demonstrate the applicability of the proposed method. The results of these two matching examples illustrate that this semiautomated method is highly effective and can meet the needs of real-world applications. The automated algorithm is capable of generating reliable matching measures, resolving difficult matches, and in both cases, correctly identifying the overwhelming majority of the matching counterparts. The interactive procedure, on the other hand, is useful for checking and correcting mismatched counterparts during the early stage of the matching process, which significantly improves performance and reliability.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) Autodesk Map 3D from Autodesk, Inc., is a new product that allows users to integrate spatial information for mapping purposes from a multitude of data sources. The software includes several analysis capabilities associated with a geographic information system (GIS) while at the same time providing the capability to work with CAD formats. Autodesk Map 3D is more than a CAD package, more than a GIS software and more than a stand-alone visualisation software that serves for mapping purposes. The software is tightly integrated to include each of these aspects and their associated capabilities. The following is a review of Autodesk Map 3D.
