[Vedettes matières IGN] GénéralisationRésumé : (Auteur) The British Geological Survey is recognizing the consumer's need for customized 'builtforpurpose'geoscientific data sets. It is witnessing a move away from being merely producers of standard scale cartographic products. This research proposes an automated tool for the generalization of geological maps, which may assist the organization in meeting these demands. The research shows that in order to derive a coarse scale geological map from a fine scale geological database there is a requirement for contextual sensitivity. To achieve an appropriate result the interaction between the themes represented on the map must be considered and should reflect the interaction of geological objects in the real world. A case study is presented which illustrates how standard cartographic generalization operations can be combined, using a rule base, into a partially automated process to generalize a geological data set from 1.50 000 to 1.250 000 scale. Independent geoscientific professionals evaluated the results from the case study. The tool provides consistency and tracabilty in the generation of multiscale geoscientific data. The evaluation suggests that, with further research, higher levels of autonomous generalization are achievable. In its current form it is a highly useful tool as a testbed for defining generalization requirements in geological mapping, an aid to the production of standard scale maps and a basis for creating customer specific data sets.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) A method is presented for generalising cartographic lines using an approach based on determination of their structure. Constrained Delaunay triangulation is used to construct a skeleton of the space surrounding the lines and hence represent line features in terms of skeleton branches. Several statistical measures are used to characterise the triangulation branches. The measures enable selective generalisation of different types of line feature, leading to the possibility of userspecification of the style of generalisation. In our implementation of the approach, the triangulation is updated dynamically to allow both sides of multiple lines to be processed, while guaranteeing topological consistency between the resulting generalised lines.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) It has been widely recognized that, in order to automate the map generalization process, cartographic knowledge needs to be formalized. One method of knowledge acquisition is to analyse existing maps. Previous studies have concentrated on describing the phenomena on the surface. A typical example is the percentage change of the number of symbols or the percentage of open space on smaller scale maps. This study aims to go one step further, i.e. to analyse the association such changes with thematic attributes. In this study, road features on topographic maps of Hong Kong from 1:1000 to 1:200 000 are studied; six types of thematic attributes, i.e. 'type', 'length', 'width', 'number of lanes', 'number of traffic ways' and 'connectivity', are considered; and two statistic parameters, Lambda and Somers' Delta, are employed. It has been discovered that the dependence of road elimination on these attributes occurs in the following order : type (0.73), length (0.53), number of lanes (0.48), number of traffic directions (0.41), width (0.36) and connectivity (0.19). If these numbers are normalized into percentages, then these values become: type (27%), length (20%), number of lanes (18%), number of traffic directions (15%), width (13%) and connectivity (7%). Such results could be used to formulate an overall weight to determine whether a particular road should be deleted, merged or combined in the generalization process, in order to retain a certain proportion of roads at a smaller scale.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) Generalisation is the task of deriving small scale or geodata products from more detailed existing mapping or source data (covering a smaller area sheet). It involves exaggerating thse aspects that are important for a particular purpose and scale, and removing unwanted detail that would otherwise clutter the map and confuse the user. Generalisation allows a series of such products to be produced from a single data source. The task, performed manually, once constituted much of the work of the traditional cartographer, being slow, tedious and error-prone. In the digital age, however, more efficient methods are possible and automating 70 per cent of the generalisation process offers huge cost-saving.
