[Termes IGN] solideRésumé : (Auteur) The goal of this research is to develop a 3D topological structure to represent a 3D space partition with validation functionality and support for conversions from topological to geometrical primitives. Several 3D topological structures have been presented in the past, mainly by researchers. The technical (implementation) model developed in this paper is based on the conceptual model of the ISO 19107 spatial schema' standard and consists of four topological primitives: node, edge, face, and volume, which are related to each other via their (co)boundary relationships. In our setting, only linear primitives (no curves) are supported and no isolated and dangling primitives are allowed. In our model, the rings, the shells, and the orientation play key roles within the topological structure and the functions that implement the geometrical realization. There was no formal definition of a valid 3D topological structure available and this paper presents such a definition, which is the main novel contribution. This definition is presented in three levels, where at every next level the definition is further refined such that finally a set of rules is proposed, which can be implemented unambiguously. In order to validate a 3D topological structure, the involved volumes must be valid as well as the whole structure, which means the relationships between the volumes. The rules for a valid structure have been implemented on top of Oracle Spatial and tested with artificial and real-world test data.

[Vedettes matières IGN] GénéralisationRésumé : (Auteur) We employ a batch generalization process for obtaining a variable-scale planar partition. We describe an algorithm to simplify the boundary lines after a map generalization operation (either a merge or a split operation) has been applied on a polygonal area and its neighbours. The simplification is performed simultaneously on the resulting boundaries of the new polygonal areas that replace the areas that were processed. As the simplification strategy has to keep the planar partition valid, we define what we consider to be a valid planar partition (among other requirements, no zero-sized areas and no unwanted intersections in the boundary polylines). Furthermore, we analyse the effects of the line simplification for the content of the data structures in which the planar partition is stored.

[Termes IGN] trace numériqueRésumé : (auteur) This paper addresses the issue of quality in the context of collaborative edition of spatial content. The overall approach is grounded on the definition of explicit and adequate specifications for such content, i.e. the data model, the conceptual model, conventions for data acquisition, possible integrity constraints, possible relationships with external reference data. Explicit specifications could be processed to automatically check when different users simultaneously contribute on the same area. Their definition requires expertness, firstly, to ensure spatial content consistency and, secondly, to establish relevant relationships with external reference data. Designing these specifications is not an easy task for contributors. Hence, the focus of this paper is to assist them in this task. We propose a generic process to automatically produce specification items such as feature types, attribute types, and relationship types, including possible relationship types with external reference data from a set of keywords. It exploits information from two different kinds of existing contents: user generated content (like Wikipedia) and more conventional content (like WordNet and NMA databases). It has been applied to keywords found in existing user generated spatial contents.
