[Termes IGN] raisonnement spatialRésumé : (Auteur) When accumulating large quantities of positional data with ubiquitous positioning techniques, methods are required that can efficiently make use of these data. This work proposes a representation that approximates motion events of pairs of objects. It is shown how the employment of formal grammars enables the interpretation of such motion events. This is accomplished by composing motion patterns into specific qualitative features. In particular, the change of relative directions defines characteristic motion events.

[Termes IGN] web sémantiqueRésumé : (Auteur) Interpretation of spatial features often requires combined reasoning over geometry and semantics. We introduce the Space package, an open source SWI-Prolog extension that provides spatial indexing capabilities. Together with the existing semantic web reasoning capabilities of SWI-Prolog, this allows efficient integration of spatial and semantic queries and provides an infrastructure for declarative programming with space and semantics. There are few systems that provide indexing and reasoning facilities for both spatial and semantic data. A common solution is to combine separate semantic reasoning and geospatial services. Such loose coupling has the disadvantage that each service cannot make use of the statistics of the other. This makes optimization of such a service-oriented architecture hard. The SWI-Prolog Space and Semantic web packages provide a native Prolog interface to both spatial and semantic indexing and reasoning, which makes it easy to write combined query optimizers. Another advantage of the Space package is that it allows declarative logic programming, which means in practice that you say what you want to compute instead of how to compute it. The actual indexing machinery is encapsulated inside Prolog predicates. In this article we describe the interface of the Space package, compare its functionality to alternative software libraries, and show how to work with it using three example applications. These example illustrations include reasoning over movement patterns, dynamically loading geospatial linked data off the semantic web, and setting up a simple KML server.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) In practice, descriptive localities are often communicated using named places and spatial relationships. Uncertainty associated with such descriptions of localities is inevitable, and knowledge of such uncertainty is normally not explicit. When translating descriptive localities into spatially explicit ones, it is critical to circumscribe locations and to estimate the associated uncertainty based on a set of appropriate spatial relationships. In conventional research on qualitative spatial reasoning (QSR), spatial relationships are modeled using formal logic. Unfortunately, QSR cannot deal with the uncertainty of a position. In this paper, based on the conceptual model of spatial assertions, we introduce the uncertainty field model to represent the probability distribution of a point locality. Using probability operations, we can combine a set of assertions to position a locality. Conflicts among assertions for a single locality can be detected based on the resulting field. Since spatial relationships play an important role in the uncertainty of target objects, we investigate conceptually the uncertainty fields associated with various types of spatial relationships (for example, topological, directional and metric). In a concrete application, these uncertainty fields can be customized and used without altering the proposed framework.

[Termes IGN] toponymeRésumé : (Auteur) Spatial processing is increasingly prevalent in the modern computing milieu. In particular, geographic information retrieval and location-based services such as GoogleEarth and MapQuest depend on spatial operations in conjunction with gazetteers to georeference geographic features. However, many gazetteers contain only point locations or simple bounding rectangles, which make for erratic and sometimes poor georeferencing. Convex hulls can provide better georeferencing results at modest computational cost, but their shape fidelity is still erratic. Full GIS capabilities are actually overfit for many geospatial and georeferencing purposes, because of the limited accuracy of the underlying data. The financial and technical demands of GIS also exclude it from many markets. Described here is a new technique, multihulls, based on the iterative refinement of convex hulls. Multihulls achieve arbitrary shape fidelity at a small increment in computational cost, consistent with the data, outside a GIS, making them attractive for many geospatial and georeferencing applications, especially gazetteers.

[Termes IGN] raisonnement spatialRésumé : (Auteur) This paper presents an approach to build and mobilize spatial thinking in civil engineering education. The approach is based on experiences in the Department of Civil Engineering at the University of Manitoba, and is illustrated by describing pedagogical strategies used in undergraduate and graduate teaching, and providing examples of spatial learning by civil engineering students. The approach addresses the need to build students' spatial thinking capacity by teaching geospatial concepts and theory in concert with practical application of the theory through hands-on experience with geospatial technologies and software, involvement in real-world civil engineering projects, and integration with industry experts. Advancements of spatial thinking technologies and their ubiquitous and rapid adoption by society challenge civil engineering educators to equip students with the advanced skills required to meet rising expectations of their spatial thinking capacity.
