Résumé :	(Auteur) Lettering is of prime importance for maps, but positioning is a time-consuming process which may account for up to 50% of the map-editing. This paper addresses the main parameters that lead positioning, and the problems entailed. Then an approach for automated road administrative name-placement is presented which takes into account these problems. We have implemented a research system which follows this approach. The results achieved so far indicate that the problem modeling we used allows to meet high quality requirements.

Résumé :	(Auteur) This paper proposes to describe geometrical characteristics of linear features by segmenting lines and qualifying sections detected according to different criteria at several levels ("hierarchical" process). Such a kind of line representation should provide basic and complementary information in order to guide global and local decisions. The ultimate aim is to choose and sequence adequate generalization tools and parameter values.

Résumé :	(Auteur) In 1991, an experiment began at IGN at the COGIT laboratory. Its objective was to examine the potential of object-oriented technology in manipulating and modelling geographical objects. From an experimental point of view, a prototype has been developed on top of a commercial DBMS, namely O2, from (^Technology. The prototype has been called GeO2- This article gives an account of the most prominent experiments that have been carried out at this stage of development. We concentrate on the management of large volume of data and look at processes which could be affected by it: loading, visualizing, accessing to (through a spatial index). A test of portability on C++ storage system is also mentioned. Then results of our experiments allow us to shed new light on object-oriented technology.

Résumé :	(Auteur) The Hausdorff distance between two objects is a mathematically true distance. When both objects are punctual, it does not differ from the Euclidean distance between points; otherwise it takes into account the mutual positions of the objects relatively to each other. Its main interest for automated cartography, besides quantifying spatial relations between objects, lies in the fact that it expresses remoteness. How far are features from each other? How far is a generalized feature from its original position? After spotlighting on some properties of the Hausdorff distance applied to geographical features, the paper describes an algorithm for computing the Hausdorff distance in vector mode between two polylines.

Résumé :	(Auteur) Generalization may be defined as a controlled reduction and simplification of geographical data. Despite the knowledge of basic generalization operators, the automation of generalization remains a complex issue. Actually the change in resolution induces numerous spatial conflicts and the use of generalization operators such as smoothing or aggregation may accidentally degrade geographical data. The aim of this paper is to propose a set of paradigms necessary to automate generalization. Firstly a space partitioning computed from structuring objects allows to define some working areas and to give a pre-sequence of transformations in the process of generalization. Then some local Delaunay triangulations allow to compute proximity relations between non-connected objects and to propagate displacements due to some geometric transformations. To ensure consistency during different geometric changes, both paradigms are integrated with a classical topometric structure.
