Book Synopsis Intégration et recherche de données environnementales dans un système d'information by : David Verdin
Download or read book Intégration et recherche de données environnementales dans un système d'information written by David Verdin and published by . This book was released on 2006 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disposer de connaissances fiables et claires sur un problème constitue un préalable indispensable à une prise de décision raisonnable et argumentée. Les données sont la première source de connaissance en environnement, or elles sont rares et souvent inaccessibles. Ces données sont hétérogènes et dispersées au sein de diverses structures et organismes publics et privés. Etant donné leur coût d'acquisition, il nous semble préférable de favoriser leur réutilisation. Nous proposons une architecture pour un système d'information dont le but est l'identification et la localisation de jeux de données environnementales. Afin de remédier à l'hétérogénéité et l'éparpillement des données, nous créons un système qui n'impose pas de modifier la structure actuelle et le fonctionnement institutionnel de la gestion de l'environnement. Nous décrivons les données environnementales afin d'établir des fiches de métadonnées. Ceci rend aisée l'intégration de tous types de jeux de données dans notre système. L'intégration de métadonnées issues de jeux de données par nature très variés pose rapidement deux problèmes sémantiques : l'interprétation des termes employés pour les décrire et la diversité des requêtes que l'on peut adresser à notre système. Pour les résoudre, nous organisons le traitement des requêtes autour d'une ontologie de l'environnement, dont le rôle est d'enrichir notre système de connaissance environnementales et faciliter l'interprétation des requêtes qui lui sont adressées. Ces connaissances sont exploitées en parcourant le graphe de concepts que constitue l'ontologie et en évaluant la pertinence des concepts rencontrés par rapport à la requête.

Book Synopsis Systèmes d'information environnementaux et d'aide à la décision by : Collectif,
Download or read book Systèmes d'information environnementaux et d'aide à la décision written by Collectif, and published by . This book was released on 1998 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les systèmes d'information géographique sont conçus pour structurer, gérer, analyser et communiquer l'information géographique. Ces outils deviennent stratégiques tant pour l'observation économique ou environnementale des territoires que pour organiser les actions que l'on veut conduire sur ces territoires. Ces systèmes permettent d'évaluer les impacts d'une décision ou de simuler des scénarios d'évolution. Ils constituent donc une solution primordiale pour les collectivités locales dans le domaine de l'aménagement du territoire, de l'urbanisme ou de la gestion de l'eau. Les missions de SIGURA (Centre de ressources SIG en Rhône-Alpes) sont, entre autres, d'être un Centre de ressources et de compétences où les chercheurs peuvent faire bénéficier les entreprises et collectivités locales des avancées les plus récentes en matière de traitement de l'information géographique en intégrant modélisation, statistique, géographie, télédétection aérienne ou spatiale. Les divers acteurs du développement au niveau de la région et des départements pourront y trouver les experts nécessaires pour traiter l'information, la structurer, la représenter et la synthétiser grâce à des outils d'analyse spatiale adaptés. Les sept articles qui sont présentés dans ce numéro spécial et qui ont été sélectionnés à partir des communications de SIGURA 97, portent sur trois thèmes représentatifs des avancées en recherche appliquée dans le domaine des SIG en Rhône-Alpes. Ces avancées répondent à des problématiques de niveau différent mais d'actualité. Comment améliorer la qualité et la mise à jour des bases de données géoréférencées ? L'analyse spatiale des risques environnementaux (avalanches, glissements de terrains, pollutions, etc.) permet-elle de mieux les gérer ? Comment le traitement de l'information géographique s'intègre-t-il dans un processus d'aide à la décision pour la gestion environnementale des territoires ?
