[Vedettes matières IGN] GénéralisationRésumé : (Auteur) Recent models and systems of generalisation allow to produce new representations of geographical information according to generalisation constraints. One of the shortcomings is that they still can not be tuned easily according to different user needs. In the present paper, we propose an implemented system made of web interface and specific modelling and engine that proposes a user with a set of already generalised objects used to identify his needs. The principle is to create a sample data base that contains the information related to the constraints used to obtain a large set of different types of generalisation. These samples are proposed to the user who chooses the solutions that look like what he is looking for. Behind the interface, the system analyses the answers to gradually converge towards the optimal final parameter values, if possible. Natural language has been added for the first step of the query to being more flexibility and to allow some qualitative reaction of the user (such as 'bigger' or 'with less details'). As a first try the work has been limited to the generalisation of buildings but the data modelling has been conceived in a generic way to allow the extension to other types of objects.

[Termes IGN] orientationRésumé : (Auteur) This paper deals with the automation of the cartographic generalisation and proposes a new measure of the orientation of a building. The description of this characteristic is a complex issue, as if the computing of orientation is relatively clear for a segment or a line, this is not the case for a polygon. Thus, existing measures of orientation are briefly reviewed. Our measure is inspired by the measure of building orientation of walls, modulo . The proposed modification is an adaptation of this measure modulo /2, associated with a confidence indicator on it, and is called Wall statistical weighting. We show that this new measure can be combined with existing ones to better describe and generalise buildings.

[Termes IGN] utilisateurRésumé : (Editeur) The Design and Implementation of Geographic Information Systems provides a unique nuts-and-bolts perspective of enterprise GIS design, a geographic information system that meets the needs of numerous users across multiple units in an organization. This hands-on guide offers in-depth, up-to-date material on issues of spatial data when designing and implementing enterprise GIS, along with insightful, illustrative examples. From the predesign planning stages dealing with assessment, requirement analysis, organizational issues, and cost analysis, to integrating legacy MIS systems and preparing for future developments in database design, this user-friendly book addresses all the fundamental aspects of the design and implementation of GIS, regardless of soltware or hardware. It offers helpful "decision trees" to assist in strategic planning, as well as proven strategies for application development, interface design, and enabling Web-bases access. Numerous case studies and examples from the private and public sectors demonstrate how these strategies and approaches play out in the real world. Note de contenu : CHAPTER 1 - INTRODUCTION

[Termes IGN] simulationRésumé : (Auteur) This paper deals with the integration of vector data into a digital terrain model (DTM) to perform flood risk analysis. The integration of geographic 2D vector objects into a DTM usually raises data coherence issues. To address these issues, 2D objects are transformed into 2,5D objects and then integrated into an enriched DTM in a coherent way. We focus our research on objects describing civil engineering works such as roads, dikes, or embankments. Such a coherent integration of 2D objects into a DTM can change flood behaviour simulations deeply and thus predicted damage areas. The first part of this paper describes the general methodology used for road integration. Simple placing of 2D linear roads on a DIM generally gives unrealistic results. Our approach consists in transforming 2D linear data into 2.5D surfaces describing terrain in a more realistic way. We transform 2D linear roads into 2.5D surfacic roads by assigning them a width, and computing their elevation. The altitude of each point of the road is computed with the help of the DTM and the altimetric attribute of nodes, under slope and regularity constraints. Then, we compute a new DTM, resulting from the original DTM constrained by the 2.5D roads. We observe that this integration alters the DTM locally. The second part reports on the analysis of a DTM after the integration of roads. We base our analysis on two main applications: visualisation and hydrology. As roads were initially captured at a much higher scale than the DTM, the creation of a microrelief is observed. This microrelief may contain artefacts, which could create uncertain areas. The study of these areas helps us to define the range of scale and the validation of such methods. By comparing the results obtained by hydrological simulation with our refined DTM and with the initial DTM, we highlight the precision and coherence gained when using this enriched DTM. With our algorithms. the new DTM is more accurate on certain keyareas such as dikes or roads, which are civil engineering works that are very important for flood simulations. The third part focuses on the implementation of these algorithms in an experimental Java GIS platform, linked to an Oracle 9i database. Then this part report on the analysis of our TIN enrichment. The original TIN is locally modified. Some inconsistencies between the original TIN and the vector data are fixed thanks to the integration of new 2.5D information. For example, in the enriched TIN, rivers follow the talwegs. Without 2.5D vector information, talwegs are interpolated from contour lines and are not consistent with the river network. As a conclusion, we suggest that our work can be extended to fit other applications, such as trajectory computation.
