The SDH conference series has been organised as one of the main activities of the International Geographical Union (IGU) since it was first started in Zurich in 1984. In the late 1990’s the IGU Commission of Geographic Information Systems was discontinued and a study group was formed to succeed it in 1997. Much like the IGU Commission, the objectives of the Study Group are to create a network of people and research centres addressing geographical information science and to facilitate exchange of information. The International Symposium on Spatial Data Handling, which is the most important activity of the IGU Study Group, has, throughout its 18 year history been highly regarded as one of the most important GIS conferences in the world.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) Generalisation is well recognised as a complex process that should trigger specific algorithms, on different types of objects in some logical or appropriate order. To guide the process (where and how to generalise) one solution is to distinguish characterisation from the generalisation process. Characterisation aims at finding and describing relevant 'working areas' that can be a part of an object or a set of objects. As a result, the choice of an appropriate algorithm(s) becomes easier and can be constrained by the detected properties of this new entity. This paper presents a method to both detect and characterise building alignments in an effort to improve the use of generalisation algorithms namely typification and displacement. The first step consists of the identification of building alignments from straight-line templates. The second step characterises these alignments to retain only those that are perceptually regular. The characterisation is based on an analysis of the spatial location of buildings as well as on the properties of the buildings that belong to the alignment in question. To evaluate the regularity of the distribution, estimators are proposed for each property. At the end a global quality estimator of the perceptual alignment- based on the aggregation of the estimators - is proposed. This global estimator is used to retain the best building alignments that will then be carefully generalised. The results presented have been implemented in the Lamps2 GIS software.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) Ecology is a subject of great debate today among scientists, governments, and the general public. Issues such as global warming and biodiversity require a mutual agreement among different groups of people. Many times these groups are separated by language, political interests, and culture. Environmental Information Systems need to integrate data from different Geographic Information Systems. This may cause problems resulting from the semantic heterogeneity of the source communities. Before this kind of integration can happen among different groups, the concepts that people have about the real world must be explicitly formalized ; such an explicit formalization of our mental models is called an ontology. In this paper, we discuss two options for structuring such ontologies. First we discuss the use of hierarchies and roles in the structure of geographic ontologies. Second, we discuss some of the fundamental characteristics of ecological ontologies and draw attention to several formal differences between ecological and geographic ontologies. We conclude by identifying some of the important questions that arise in light of our conception of eco-ontologies.

[Termes IGN] requête spatialeRésumé : (Auteur) Accessing the user interfaces proposed by GISs, G-DBMS or geographic Web sites shows how complex they may prove for novice users of geographic information. Such users have needs in geographic information, but they do not have the means to express them and thus to adequately fulfil them. The objective of this paper is to outline an approach that may help users specify their needs with geographic information. This approach consists in converging on one available solution, the closest possible to the user needs, by using new means of communication between user and computer: map samples and natural language. Map samples are geographical data, extracted from the database and possibly processed by available GIS treatments. A few map samples are proposed to the user, who makes the relevant choices. The system tries to "understand" the interactions to help in the choosing. A search engine navigates through the available map samples in order to identify the most appropriate map samples and proposes them to help the user identify the need more precisely. Natural language allows the expression of user needs to be captured in a manner more consistent with a dialogue and provides more freedom or versatility for example, for general queries and quantitative evaluation. A virtual scenario shows the combination between these two languages.
