[Vedettes matières IGN] GénéralisationRésumé : (Auteur) The detection of spatial conflicts is one of the main issues in digital generalization. This paper describes some mathematical models for this purpose. These models are based on the basic operators developed in mathematical morphology which is a science of shape. More concretely, an operation called translation (or transportation) is realized using morphological operators ; then, this translation operator is used for detection of spatial conflicts. The detection is achieved by a translation and then an overlay operation. These models are experimented with real map data.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) Generalization is a very important topic in cartography/GIS. After generalization, a process called displacement might be required for the following reasons : (a) features being coalesced due to a reduction in graphic space available ; (b) spatial conflicts being created by inappropriate algorithms or procedures ; (c) the characteristics of the structure of some maps features (i.e. a road junction) needing to be kept. In this study, two types of feature displacement are distinguished, i.e. feature translation and feature modification. Some mathematical models for both types of displacement are presented, which are based on the operators developed in mathematical morphology which is a science dealing with form, shape, and structure of objects. These models have also been experimented using real map data sets. The results show that these models are very promising.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) This paper describes some algebraic models for the automated generalization of area-patches. These models are based on techniques developed in mathematical morphology, which is science dealing with the form and shapes of objects, and will form an algebraic basis for area-patch generalization. These models are fully illustrated and tested. The results show that such models are very promising.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) This paper intends to discuss the nature or essence of digital map generalisation. Existing work is examined and new views are expressed. First of all, the motivation of generalisation is discussed. It is then grouped into two types, i.e. direct and indirect motivation and it is argued that scale is the only element in direct motivation. Based on this argument, two fundamental processes in digital map generalisation are distinguished, i.e. transformation of reality in scale dimension (digital data generalisation) and digital topographic transformation (graphic presentation). Finally, a framework is devised for both of these two processes.
