[Vedettes matières IGN] GénéralisationIndex. décimale : 37.70 Généralisation Résumé : (auteur) Cartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. Two topics are treated: optimisation methods in graphic generalisation, and propagation of updates between cartographic data sets of different scales. To enable an optimisation approach to graphic generalisation several topics are studied. Firstly, requirements are stated for defining a good map. These requirements can act as constraints and control the graphic generalisation process. In this thesis, ten analytical constraints for graphic generalisation are proposed, some for single objects and some for groups of objects. Rules are also established regarding when these constraints should be set up. Secondly, the least-squares method is studied as an approach to finding the optimal solution according to the constraints. Related to this, weighting strategies for the constraints are also discussed. Thirdly, computationally efficient methods are tested, which are especially important for establishing spatial relationships between objects and solving the large normal equation systems. Finally, the optimisation approach has been evaluated visually and quantitatively in mid-scale applications. Mapping organisations have to maintain cartographic data sets of different scales (resolutions). Ideally, mapping organisations should only be concerned with updating the most detailed data set and the updates should automatically be propagated to all other data sets. In this study, a prototype system was created for automatic propagation of updates. This system is integrated in an object-oriented map production software, in which the data sets are stored in a multiple representation database. The rules implemented in the prototype system were gathered from data set specifications and by studying printed map series. The propagation of updates performed by the prototype system was compared with manual propagation performed by a cartographer. Note de contenu : 1- Introduction

[Termes IGN] objet géographique zonalRésumé : (Auteur) With the help of highly advanced cartographic software programs it is possible to produce topographic maps from digital data. In some cases, however, there exist graphical conflicts, because symbol widths require more space than their real-size equivalents. Generalization of such objects by manual editing is rather time-consuming. Therefore, automation of generalization operations is desirable and should be possible in the age of information technology.
Automated cartographic displacement of vector data distinguishes between point, line and area objects subject to processing. Modeling of line objects assumes a central position, because the human eye is extremely sensitive to shape alterations caused by displacement. In many applications splines are well-known tool for describing lines. It is especially the energy-minimizing spline also called snakes model shape deformation as a result of external forces. The internal energy is used to maintain the line shape which has been displaced due to conflicts. First and second derivatives of the line coordinates with respect to the are length are used as quality measures. In cartographic displacement a minimal distance between adjacent objects should be maintained. The external energy is used to describe the conflict situation if objects are too close to each other.
To solve the graphic conflicts while maintaining the shape of the objects, the method of energy minimization is employed. Minimizing the energy functional of internal and external energy leads to two independent Euler equations. These are discretized by means of finite differences. The equations can be solved iteratively using the Cholesky factorization. Parametrization of the energy-minimizing splines by means of the tangent angle function (tafus) replaces the two eulerian equations of the 4th order with one equation of the 2nd order. Simplification of the equation system requires an additional amount of calculation for transforming the resulting changes of line direction to attain cartesian coordinates. Verification of a desirably faster convergence has yet to be achieved. The Greedy Algorithm is an alternative procedure to accomplish energy minimization using the Variational Calculus. With the aid of this algorithm the energy of each individual support point is minimized by way of minor displacements. As opposed to the Variational Calculus the effects are more local. Therefore, the Greedy Algorithm is advantageous used for the displacement of buildings or for the positioning of label boxes.
The integration of this displacement approach in a cartographic program provides evidence of the fact that it can be used in practical applications. Cooperation with a software producer will help to find additional fields of application, a case in point being the automated map edge work which allows displacement and suppression of text and symbols at the map boundaries. Experience has shown that the research effort required for developing new software tools is estimated to amount to between 30 and 50 percent of the total effort.Numéro de notice : 27829 Affiliation des auteurs : non IGN Thématique : GEOMATIQUE/INFORMATIQUE Nature : Thèse étrangère Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=56453 Réservation

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) This paper summarizes some of the key architectural elements and reviews some of the results of the AGENT project, a research project funded by the European Commission between 12/1997 and 11/2000 as part of the Esprit Programme. The project involved five partners and successfully developed a prototype system to deal with
automated map generalization. The prototype is based on Laser-Scan's object-oriented GIS and map production system LAMPS2, uses a multi-agent approach to model cartographic objects and their treatinent in generalization, and uses various newly developed geometric algorithms to measure and transform the cartographic objects in the generalisation process.
