[Termes IGN] système d'information géographiqueRésumé : (Auteur) Equipée d'un SIG depuis 10 ans, la ville de Lyon en ouvre aujourd'hui les portes à plusieurs milliers d'utilisateurs par le biais d'un intranet cartographique particulièrement complet. S'il est encore trop tôt pour analyser avec précision qui sont ces nouveaux consommateurs de cartes et d'information géographique, l'expérience n'en est pas moins concluante, ne serait-ce que parce qu'elle installe le SIG dans la transversalité.

[Termes IGN] Pays de GallesRésumé : (Auteur) Phase coherence between pairs of ERS SAR images is investigated as a method for mapping urban extent in South Wales, United Kingdom. Separability indices show that image pairs with time delays of greater than 2 months and baseline separations of less than 300 m can discriminate effectively between urban and non-urban land. Classification kappa coefficients greater than 90 percent are achieved, and there is evidence to suggest that a single coherence threshold is applicable for mapping urban extent in any similar landscape.

[Termes IGN] précision de la classificationRésumé : (Auteur) This study evaluated how spectral resolution of spatial resolution optical remote sensing data influences detailed mapping of urban land cover. A comprehensive regional spectral library and low altitude data from the Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) were used to characterize the spectral properties of urban land cover. The Bhattacharyya distance was applied as a measure of spectral separability to determine a most suitable subset of 14 AVIRIS bands for urban mapping. We evaluated the performance of this spectral setting versus common multispectral sensors such as Ikonos by assessing classification accuracy for 26 urban land cover classes. Significant limitations for current multispectral sensors were identified, where the location and broadband character of the spectral bands only marginally resolved the complex spectral characteristics of the urban environment, especially for built surface types. However, the AVIRIS classification accuracy did not exceed 66.6% for 22 urban cover types, primarily due to spectral similarities of specific urban materials and high withinclass variability.

[Termes IGN] variogrammeRésumé : (Auteur) In single-band and single-polarized synthetic aperture radar (SAR) image classification, texture holds useful information. In a study to assess the map-updating capabilities of such sensors in urban areas, some modern texture measures were investigated. Among them were histogram measures, wavelet energy, fractal dimension, lacunarity, and semivariograms. The latter were chosen as an alternative for the well-known gray-level cooccurrence family of features. The area that was studied using a European Remote Sensing Satellite 1(ERS1) SAR image was the conurbation around Rotterdam and The Hague in The Netherlands. The area can be characterized as a well-planned dispersed urban area with residential areas, industry, greenhouses, pasture, arable land, and some forest. The digital map to be updated was a 1: 250 000 Vector Map (VMapl). The study was done on the basis of non-parametric separability measures and classification techniques because most texture distributions were not normal. The conclusion is that texture improves the classification accuracy. The measures that performed best were mean intensity (actually no texture), variance, weighted-rank fill ratio, and semivariogram, but the accuracies vary for different classes. Despite the improvement, the overall classification accuracy indicates that the land-cover information content of ERS1 leaves something to be desired.

The development of a standard symbology for emergency and hazard maps will strengthen coordination and communication between planners and will enhance the ability of emergency managers to better understand information at a glance during crucial decision making moments. This research analysed existing emergency map symbology found in various forms, including software packages, and proposes a theoretical framework for the design of emergency mapping symbology. There has been a burgeoning use of electronic emergency management tools at all levels of government, enough to indicate that emergency management is on the cusp of an explosion of electronic map making. This is an appropriate time for guidelines and standards for hazard and emergency maps to be created.
