[Termes IGN] objet flouRésumé : (Auteur) Although most geographical entities represented as objects in a GIS have crisp boubaries, in relity they have indeterminate boundaries and fuzzy spatial extent. This is due to the fact that they are distributed continuously in space and time. Futhermore, measurement procedures generally produce data with a limited accuracy , which lead to the uncertain description of geographical entities. Because of these facts, uncertainties exist in the crisp object description of geographical entities. When temporal information is applied to analyze their change, these uncertainties will influence the final results of mapping. Therefor, the effects of the uncertainties on monitiring geographical entities should be studied, in order to provide accurate information to decision makers. This paper discusses the indeterminate nature of geographic entities and its effects on change detection when they are monitored through time. The concept of fuzzy objects and fuzzy change detection are applied to describe heterogeneous objects or objects with indeterminate boundaries. Several measures for fuzzy change detection are presented to evaluate the change processes of the objects. A pratical example of the dynamics of sediments along the Dutch coast is elaborated to demontrate the approach and the concepts proposed.

[Termes IGN] superposition d'imagesRésumé : (Auteur) Classification errors using texture are most likely associated with class edges, but investigators often avoid edges when evaluating textures for classification. The large window needed to produce a stable texture measure produce large edge effects. Small windows minimize edge effects, but often do not provide stable texture measures. Simulated data experiments showed that class separability increased when texture was used in addition to spectral information. Texture separability improved with larger windows. This improvement was over estimated when pixels were chosen away from class edges. Airborne Data Acquisition and Registration (ADAR) data showed that separability of class interiors improved with the addition of texture, but that, for the whole class, separability fell. Maximum-likelihood classification of the ADAR data demonstrated the effect of edges and multiple scales in reducing the accuracy of classification incorporating texture.

[Termes IGN] modèle numérique de surfaceRésumé : (Auteur) This paper proposes and illustrates a decision analytical approach to compare the value of alternative spatial data sets. In contrast to other work addressing value of information, its focus is on value of control. This is a useful concept when choosing the best data set for decision making under uncertainty due to error in the reported data. Application of the concept requires probabilistic accuracy measures and a loss function representing the cost of incorrect judgement about some target property. This is illustrated by an assessment of the suitability of two digital elevation models (DEMs) for determining the volume of sand required for building a container port. To demonstrate flexibility of the approach, accuracy assessment was based on both a random and a systematic sample of error data, using designbased estimation and model-based prediction, that is geostatistics. Analysis results included the expected loss for each combination of DEM and sampling strategy. These indicated that both DEMs were equally suitable for the intended use. Operational practicability of the method is highly dependent on the willingness of database producers to give access to sample information similar to the quick looks provided to potential users of remote sensing imagery.
