This article presents the Theseus Framework designed for the automatic creation of knowledge graphs (KGs) that describe the evolution of geographical divisions (GD) over time. This framework is based on an ontological model dedicated to the representation of evolving GD (e.g., divisions into regions, districts, municipalities). Both the detection a...

Nowadays, the volume of data coming from the public sector is growing rapidly on the Open Data Web. Most of these data come from governmental agencies such as Statistical and Mapping Agencies. Together, these public institutions publish territorial statistics that are of utmost importance for policy-makers to conduct various analyses of their juris...

While ontological modelling and Semantic Web technologies are sometimes used to describe knowledge domains with a spatial component, there is still a lack of semantics to describe how to present this knowledge geovisually to the end user and how to automatize the process. In this paper, we first present vocabularies to describe at a high level the...

Lorsqu’une intervention de secours est nécessaire, localiser précisément et rapidement le site sur lequel envoyer les équipes est primordial. La littérature montre que des outils de géovisualisation constituent des solutions pertinentes pour supporter des processus d’analyse d’informations dans des contextes variés. Nous nous intéressons ici au rai...

Partout dans le monde, les découpages géographiques, dont les territoires font l'objet, sont soumis à des modifications de noms, d'affiliations, de frontières, etc. Ces changements sont un obstacle à la comparabilité des données statistiques (socio-économiques, sanitaires, environnementales...) mesurées sur ces territoires sur de longues périodes....

This article is part of a research program aimed at improving the location of victims in the mountains. The search for victim location is a process involving various elements, few of them falls within the scope of our team such as the modelling of the process of spatial reasoning of the rescuer and the geovisualization of multidimensional and uncer...

The CHOUCAS project aims at helping mountain rescue services to locate a victim who describes her location by means of spatial relations with reference geographic features. In this context, the study presented in this paper aims at better understanding what reference features and spatial relations are used to locate oneself in a mountain area, with...

Deux ontologies spatio-temporelles sont présentées ici : TSN, pour Territo- rial Statistical Nomenclature, et TSN-Change. Ces ontologies permettent la description de découpages territoriaux (en polygones irréguliers), utilisés comme support à la collecte de statistiques. Elles offrent un vocabulaire pour lier les versions successives de ces découpa...

Generic algorithm for automatic matching and changes detection between two Geographic Divisions' versions. This work was supported by the French region Auvergne-Rhône-Alpes [grant number REGION 2015-DRH-0367]. ARC7 : Innovations, mobilités, territoires et dynamiques urbaines.

Through times, regions all over the world are very often subject to change (their names, their belonging, their composition, and their geometries). In this paper, we present a Semantic Matching Algorithm for automatically detecting, describing and publishing in the Linked Open Data Web, rich descriptions of changes occurring in multi-level territor...

Territories are governed, administered and observed from parti- tions of space into territorial units. All these territorial partitions change over time, for political or administrative reasons. In this paper, we present two innovative ontologies – Territorial Statistical Nomenclature (TSN) and TSN-Change – for the modeling of terri- torial partiti...

Studying past at-risk phenomena is useful to prepare against future risks. Thanks to maps, it is possible to locate historical events in their spatial context. Animation and interactivity support the analysis of the dynamics of events. This paper deals with a visual method to represent narratives of past natural risk events in a map. It is based on...

This article deals with the results of a user study, which aimed to compare two geovisualization interfaces (one interactive and one animated and interactive) displaying the chain of events during past major floods. Some limitations were identified concerning the variables measured (accuracy and speed of answer) and the tasks to be performed by use...

Most of the existing approaches for trajectory modelling propose to enrich structured spatiotemporal trajectories with semantics. In social sciences, the term of “trajectory” is often used to describe some evolution that is not necessarily related to some geographical movement. In this paper, we propose ontological design patterns that (i) allow mo...

Pour se préparer face aux risques à venir, il est utile d'étudier les événements passés issus de risques. Un support cartographique replace les événements historiques dans leur contexte spatial. Le doter d'animation et/ou d'interactivité peut permettre d'analyser les dynamiques des événements. Cet article présente des propositions de géovisualisati...

The observation of demographical, economical or environmental indicators over time through maps is crucial. It enables analysing territories and helps stakeholders to take decisions. However, the understanding of Territorial Statistical Information (TSI) is compromised unless comprehensive description of both the statistical methodology used and th...

Extreme floods occur in large territories and may cause significant damages to the railway system. As they are relatively rare, historical information about extreme floods is often not well known and used, whereas it could provide insights about: areas where the infrastructure is the most vulnerable, the resilience of the components of the railway...

Imperfections, often called ‘uncertainties’, exist in almost every spatio-temporal dataset, especially in historical data. They are of different types (unreliability, inaccuracy…) and concern every data dimension (space, time and theme). Based on previous work, this article proposes a synthesis qualitative classification of imperfection types. This...

The paper describes the various features of the BDHI database (objects, functions, content). This document database provides document sheets on historical floods from various sources: technical reports from water authorities, scientific accounts (meteorology, hydrology, hydraulics...), post-disaster reports, newspapers or book extracts... It is com...

RESUME. Nous proposons dans cet article un modèle de trajectoire sémantique qui supporte une certaine complexité dans la représentation des trajectoires. Nous considérons ainsi que la trajectoire est composée de multiples aspects qui constituent autant de perspectives selon lesquelles il est possible de l'observer. Nous permettons par ailleurs la r...

In this paper, we propose a semantic trajectory model handling complex trajectories. We consider that a trajectory is composed of multiple aspects which are all different viewpoints from which it can be observed. This model also allows for the representation of explanatory factors that influenced the episodes that compose a trajectory. We here deal...

In the field of natural risks, it is necessary to study spatio-temporal extents of historical events, which impacted a given territory. Dynamic maps are a good mean to perform spatio-temporal analyses. However, in some contexts, the printing of maps remains mandatory. Our aim was to make maps showing the locations of several major historical floods...

Après un rappel sur le contexte documentaire sur les inondations passées, cet article présente les principales caractéristiques de la base BDHI (Base de Données Historique nationale sur les Inondations) et son utilisation pour la prévention.

L'information à référence spatiale doit aujourd'hui respecter des normes pour garantir l'interopérabilité des systèmes de données. Si les normes ISO recommandées par la directive INSPIRE en vigueur sont adaptées aux données environnementales, mettre en oeuvre la directive pour des données statistiques territoriales nécessite des adaptations. Le mod...

This article describes a number of issues encountered when developing maps of past natural phenomena in the field of volcanology. In order to enable experts to exploit geographical data related to this topic, maps showing the temporal chronology of such events are required. Developing useful maps are made more complex by the coexistence of numerous...

Then, we compare HyperAtlas, a generic tool for multiscalar territorial analysis that we have developed, with the existing softwares that deal with spatial analysis and, among them, some that specifically addr...

Spatial OLAP refers to the integration of spatial data in multidimensional applications at physical, logical and conceptual levels. The multidimensional aggregation of geographic objects (geographic measures) exhibits theoretical and implementation problems. In this chapter, the authors present a panorama of aggregation issues in multidimensional,...

La caractérisation de l’aléa éruptif d’un volcan effusif tel que le Piton de la Fournaise s’appuie sur l’élaboration d’un certain nombre de cartes représentant la répartition spatiale des phénomènes observés dans le temps lors des différentes éruptions, à savoir fissures, fractures, coulées, cônes, séismes... Le caractère temporel des phénomènes ét...

This paper presents a platform, called QualESTIM, for exploring socioeconomic statistical data (also called indicators). QualESTIM integrates various outlier detection methods that make it possible to evaluate the logical consistency of a dataset, and its quality in fine. Without recourse to ‘ground truth’ of some kind, data values are compared to...

HyperAtlas est un outil de mesure et de cartographie des inégalités territoriales. De par les méthodes d'analyse qu'il intègre et les usages qui peuvent en être fait, HyperAtlas se situe à l'interface entre le scientifique et le politique. On se propose de questionner, dans le cadre du paradigme weberien, les usages politiques possibles d'un outil...

Introduction From AROM to AROM-ST AROM-ST From AROM-OWL to ONTOAST Architecture Community Conclusions and prospects Bibliography

The wide dissemination and use of statistics about territories has induced a need for more validation and understanding about those data. We propose an interface that eases the exploration of spatio-temporal data using an interactive cartographic tool by showing data with their metadata simultaneously. This system helps to check the consistency of...

This research aims at taking into account the mutations of the various zonings that are used to collect statistical data. The focus is on the conception of a model that handles the mutations of units that are composing those zonings, based on the building of the units’ genealogy. An automation of the update process of such a model is highly desirab...

Users of mobile devices can nowadays easily create large quantities of mobile multimedia documents tracing significant events attended, places visited or, simply, moments of their everyday life. However, they face the challenge of organizing these documents in order to facilitate searching through them at a later time and sharing them with other us...

In this chapter, we propose a context-aware filtering process for adapting content delivered to mobile users by Web-based Groupware Systems. This process is based on context-aware profiles, expressing mobile users preferences for particular situations they encounter when using these systems. These profiles, which are shared between members of a giv...

documentation des données recueillies et utilisées dans les systèmes d'information géographique est essentielle pour rendre possible leur découverte, l'échange et l'interopérabilité entre différents systèmes. Cette importance est soulignée par la directive INSPIRE, qui préconise l'usage de la norme ISO19115 pour la création de métadonnées, avec la...

The documentation of data used in any Geographical Information System (GIS) is essential for the share, the exchange, and the interoperability between various systems. This fact has been highlighted by the INSPIRE directive at the European level, whose recommendations are to create and maintain metadata based on the ISO19115 standard, and to permit...

In 2002, Egenhofer described his conceptual vision of the future geospatial semantic Web. As a contribution towards the concretization of this approach, we propose here a spatial ontology that can be used to attach spatial characteristics to Web resources, coupled with a spatial reasoner, called ONTOAST. Our work is applied to the field of semantic...

RÉSUMÉ. Ces dernières années, le web propose un nombre croissant de documents multimédia géoréférencés. Cependant, ces informations de localisation, ainsi que les autres types de métadonnées, sont encore mal exploités par les systèmes multimédia et par les moteurs de recherche. Nous décrivons dans cet article une approche pour enrichir et incorpore...

The authors of this chapter present a two-fold approach for adapting content information delivered to a group of mobile users. This approach is based on a filtering process which considers both the user's current context and her/his preferences for this context. The authors propose an object-based context representation, which takes into account th...

Semantic analysis is a new search paradigm for the Semantic Web, which aims the automatic extraction of semantic associations existing between individuals described in RDF(S) graphs. In order to infer additional semantic associations and to increase the accuracy of the analysis, we propose here, to adapt semantic analysis for OWL-DL ontologies.We a...
