[Termes IGN] trace numériqueRésumé : (Auteur) The Web is changing the way people share and communicate information because of emergence of various Web technologies, which enable people to contribute information on the Web. User-Generated Geo-Content (UGGC) is a potential resource of geographic information. Due to the different production methods, UGGC often cannot fit in geographic information model. There is a semantic gap between UGGC and formal geographic information. To integrate UGGC into geographic information, this study conducts an ontology-based process to bridge this semantic gap. This ontology-based process includes five steps: Collection, Extraction, Formalization, Mapping, and Deployment. In addition, this study implements this process on Twitter messages, which is relevant to Japan Earthquake disaster. By using this process, we extract disaster relief information from Twitter messages, and develop a knowledge base for GeoSPARQL queries in disaster relief information.

[Termes IGN] séismeRésumé : (Auteur) Remote sensing technology is a powerful tool to extract regions damaged after an earthquake. There are two methodological approaches in detection of earthquake damage: mono-temporal and multi-temporal. Especially for providing effective emergency management, the mono-temporal approach is generally preferred in extraction of earthquake damage as it does not depend on availability of pre-earthquake imagery. For this purpose, a novel method called support vector selection and adaptation (svsa) has been introduced to detect the damaged regions from a post-earthquake image. In this study, the SVSA method was applied to the region where the Haiti Presidential Palace and Cathedral is located, and the damaged regions were identified. The performance of the SVSA method in identification of the damaged regions was evaluated by comparing the thematic maps obtained by classifying pre- and post-earthquake images. Additionally, the damage patterns for the city of Port-au-Prince were estimated by the SVSA.

[Termes IGN] zone à risqueRésumé : (Auteur) The research presented in this article is based on a new technique governed by three different statistical indicators determined for each causative parameter, viz. highest density, average density and coefficient of variation of landslides. Each of these indicators was assigned a rank value between 1 and 14 depending upon its variation among the 14 causative parameters. The aggregate of the three types of rank values estimate the total ranking value (TRV) for each causative parameter. The study area is divided into 78,256 spatial units and for each such spatial unit, the influence of the different causative parameters is determined as the product of the experts' weight of the associated sub-category and the TRV of the causative parameter that categorizes the study area into various zones. The efficacy of the proposed technique is demonstrated by the occurrence of significantly high prediction accuracy of 84%.

[Termes IGN] superposition d'imagesRésumé : (Auteur) A methodology for automated extraction of damage indication from very high spatial resolution satellite imagery is presented for the Haitian towns of Carrefour and Leogane following the January 2010 earthquake. Damaged buildings are identified by changes to their shadows between pre- and post-event data. The approach makes use of object-based image analysis concepts to extract relevant information on damage distribution. The methodology selected requires pre-and post-disaster images with similar sun angles and will only be suitable for the detection of collapsed (or partly collapsed) structures. The new methodology proved to be effective for the Carrefour area despite using satellite images of different qualities with inadequate image (co-)registration, producing positively validated results within an acceptable processing time, and was, to the best of our knowledge, the only automated damage assessment method to have delivered appropriate results to requesting relief organizations within a few days of the Haiti earthquake.
