[Termes IGN] transport publicRésumé : (Auteur) The Geospatial Public Transport Information available for the United Kingdom on the World-Wide Web is evaluated. Searches for relevant websites were made at different geographical scales; the breadth of content covered and level of technology used was assessed for each site found. Public Transport Maps on each website were rated according to eleven aspects of cartographic design and Web functionality. It was found that interactivity (represented by the use of higher technology) was greater for websites giving Public Transport Information for larger areas; however, the majority of information was communicated through text or static maps. The use of colour and symbology was generally found to be good in Public Transport Web maps, but marginalia was often insufficient and hardcopy printing sometimes inadequate, limiting the usability of the maps. A number of guidelines for good practice in the production of Public Transport Web maps are suggested, stressing the importance of clarity and legibility, plus some comments on website functionality.

[Termes IGN] triangulation de DelaunayRésumé : (Auteur) This paper introduces a new algorithm for constrained Delaunay triangulation, which is built upon sets of points and constraining edges. It has various applications in geographical information system (GIS), for example, iso-lines triangulation or the triangulation of polygons in land cadastre. The presented algorithm uses a sweep-line paradigm combined with Lawson's legalisation. An advancing front moves by following the sweep-line. It separates the triangulated and non-triangulated regions of interest. Our algorithm simultaneously triangulates points and constraining edges and thus avoids consuming location of those triangles containing constraining edges, as used by other approaches. The implementation of the algorithm is also considerably simplified by introducing two additional artificial points. Experiments show that the presented algorithm is among the fastest constrained Delaunay triangulation algorithms available at the moment.

[Termes IGN] surveillance de l'urbanisationRésumé : (Auteur) We have exploited the capability of the differential synthetic aperture radar (SAR) interferometry (DInSAR) technique, referred to as Small BAseline Subset (SBAS) approach, to analyse surface deformation at two distinct spatial scales: a low resolution, large scale, and a fine resolution, local scale. At the large scale, the technique investigates DInSAR data with a ground resolution of the order of 100 m*100 m and leads to generate mean deformation velocity maps and associated time series for areas extending to some thousands of square kilometres. At the local scale, the technique exploits the SAR images at full spatial resolution (typically of the order of 5 m*20 m), detecting and analysing localized deformation phenomena. The study is focused on the city of Rome, Italy, and we used the ERS-1/2 satellite radar data relevant to the 1995-2000 time period. The presented results demonstrate the capability of the SBAS approach to retrieve, from the low-resolution DInSAR data, large-scale deformation information leading to identify several sites affected by significant displacements. Our analysis permitted us to conclude that a major contribution to the detected displacements is due to the consolidation of the alluvial soils present in the area, mostly enforced by the buildings' overload. Furthermore, in a selected area, a detailed analysis was carried out by exploiting the full resolution DInSAR data. In this case we investigated deformation phenomena at the scale of single buildings. As key result we showed that differential displacements of few mm a-1, affecting single man-made structures or building complexes, could be detected, thus allowing to identify sites that may potentially be involved in critical situations.

The required steps are explained and the emphasis is put on the minimization of distortions arising from the curvature of the earth and the inevitable length distortion of the map projection. We recall first the theoretical possibilities of dealing with the vertical distortions due to DG and then introduce a specifically developed technique for their compensation. Afterwards, we demonstrate the influence of such compensation on real examples of small- and large-scale mapping projects. Finally, we offer a comparison with two leading methods and show how these could benefit from extended modeling of the height correction.
