[Vedettes matières IGN] GénéralisationRésumé : (auteur) The nature of map generalization may be non-uniform along the length of an individual line, requiring the application of methods that adapt to the local geometry and the geographical context. Geographical databases need to be enriched in terms of shape description structures (geometrical knowledge), knowledge of appropriate order of operations and of appropriate algorithms (procedural knowledge). Stored knowledge should take account of semantic and morphological characteristics, and of cartographic constraints.
This paper proposes and discusses three experiments on knowledge acquisition using unsupervised and supervised learning techniques. In order to exploit geometrical shape knowledge, classifications were computed according to a set of morphological measures using unsupervised learning. Choice of appropriate operations was determined by the results of a test with IGN cartographers considering line characteristics. These results were given to a supervised learning algorithm, along with corresponding computed measures in order to discover rules. The approach and the resulting rules are presented and discussed. Tests have also been conducted on the tuning of parameter values, applying a Gaussian smoothing tolerance value to a set of lines using the supervised learning algorithm. The values obtained by means of the learning algorithm have been compared with interactive choices of an expert. Results are promising with a prediction rate higher than 80% having been obtained.Numéro de notice : A1998-144 Affiliation des auteurs : COGIT+Ext (1988-2011) Thématique : GEOMATIQUE Nature : Article nature-HAL : ArtAvecCL-RevueIntern DOI : 10.1023/A:1009753320636 En ligne : http://dx.doi.org/10.1023/A:1009753320636 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=98052

[Vedettes matières IGN] GénéralisationIndex. décimale : MX Mémoires divers Résumé : (Auteur) A successful implementation of a cartographic expert system for automated map generalization requires formalization of cartographic knowledge in the form of production rules. Unfortunately, empirical research for the acquisition of cartographic knowledge is lacking, and forms a major impediment towards the development of a full-scale expert system. The main motivation for this research is to contribute to the acquisition and formalization of cartographic knowledge through a computer-assisted inventory of the Austrian National Topographic Map Series. The inventory includes settlement, transportation and hydrographic features from the same geographical region at 1:50,000, 1:200,000 and 1:500,000. Map feature information is archived using a relational database, to facilitate comparisons between map scales. Cartographic information acquired through queries of the relational database leads to the formulation of prototype rules. One set of rules describes the selection behavior of settlement, hydrography and transportation under changing map scale. A second set of rules expresses the degree of simplification for settlement objects through multiple scale. The possible influence of different building functionalities and regional types is taken into consideration as well. The interaction between different map domains or different map objects is formulated in a third set of rules. Some rules seem to be very obvious, others express very detailed information. Further comparative empirical studies, focused on the acquisition of cartographic knowledge, will throw light upon the usefulness of the inventory approach and the validity of prototype rules derived from it.
