[Termes descripteurs IGN] tsunamiRésumé : (auteur) Preventing people exposed to natural hazards is a fundamental lever to reduce their vulnerability and the associated risk. In this context, evacuation maps can be considered as a useful tool to educate populations in order to get an appropriate behavior in case of disaster, and to maintain a culture of the risk in exposed areas. Since the catastrophic events in the Indian Ocean and Japan, local initiatives for the creation of tsunami evacuation maps have developed worldwide. However, no clear recommendations for the elaboration of these maps have already been proposed. This lack concerns the methods and rules used to create and represent the information present in the map. So, this article seeks to provide consensual symbolization rules for tsunami evacuation maps. To achieve this objective, a critical analysis was conducted from a sample of 30 tsunami evacuation maps. As a result, major trends and recurring choices have been extracted and compiled in a proposition for symbolization rules. This proposition, which has been implemented on various sites in the Mediterranean and Caribbean seas, can be seen as a first contribution for the harmonization of tsunami evacuation maps, in order to provide a universal cartographic language for exposed populations.

[Termes descripteurs IGN] zone urbaineRésumé : (auteur) This research presents a processing workflow to automatically find damaged building areas in an urban context. The input data requirements are high-resolution multi-view images, acquired from airborne platform. The elevations are derived from a dense surface model generated with photogrammetric methods. With the principal objective of rapid response in emergency situations, two different processing roadmaps are proposed, semi-supervised and unsupervised. Both of them follow a two-step workflow of building detection and building health estimation. Optionally, cadastral layers may serve as a-priori knowledge on building location. The semi-supervised approach involves a data training step, while the unsupervised approach exploits the similarities and dissimilarities between sets of features calculated over the detected buildings. The change detection task is formulated as a classification task defined over a conditional random field. The algorithms are evaluated using two datasets (Vexcel and Midas cameras) and results are compared with ground truth data and specific metrics.

[Termes descripteurs IGN] risque naturelRésumé : (Auteur) Natural hazards demand a rapid assessment of the crisis situation and the use of Geomatics platforms, sensors and techniques can efficiently answer this need. Remotely sensed data can, in fact, provide a valuable source of broad scale information at each stage of the disaster management cycle, supporting scientists and authorities in the decision-making process. Geomatics-based procedures and techniques can be especially exploited in the emergency mapping domain for the extraction of reference (pre-event) and crisis (post-event) geographic data. The major challenges today concern the efficient selection (and integration) of the most fit-for-purpose mapping solution(s) and the development of automatic procedures to increase efficiency in data processing. This survey article provides a review of the current optical remote sensing sensors (both satellite and airborne) for rapid mapping applications. Advantages and disadvantages are evaluated in order to support the selection process of the most appropriate means to gather the required information (i. e., significant and value-added data). Since valuable information should be delivered in a very short time, the management of time is defined as a priority and several solutions are discussed to pursue efficiency in both data acquisition and processing. With this in mind, the most significant issues affecting time in each step of the work-flow and overall accuracy are analyzed and reported.

Titre : Satellite image collection modeling for large area hazard emergency response Type de document : Article/Communication Auteurs : Shufan Liu, Auteur ; Michael E.

[Termes descripteurs IGN] traitement d'imageRésumé : (auteur) Timely collection of critical hazard information is the key to intelligent and effective hazard emergency response decisions. Satellite remote sensing imagery provides an effective way to collect critical information. Natural hazards, however, often have large impact areas – larger than a single satellite scene. Additionally, the hazard impact area may be discontinuous, particularly in flooding or tornado hazard events. In this paper, a spatial optimization model is proposed to solve the large area satellite image acquisition planning problem in the context of hazard emergency response. In the model, a large hazard impact area is represented as multiple polygons and image collection priorities for different portion of impact area are addressed. The optimization problem is solved with an exact algorithm. Application results demonstrate that the proposed method can address the satellite image acquisition planning problem. A spatial decision support system supporting the optimization model was developed. Several examples of image acquisition problems are used to demonstrate the complexity of the problem and derive optimized solutions.

[Termes descripteurs IGN] vitesseRésumé : (Auteur) Construction of scaled-down landslide models is an important means for landslide study. The objective of this study is to develop an innovative non-contact photogrammetric system to meet the challenge for monitoring the fast surface deformation of a laboratory-simulated landslide, which can detect pre-failure events and the final failure, provide sectional and overall surface deformation patterns, and generate speed maps during the rapid slope failure. We proposed an event detector based on altered surface features in the slower SLRC (single-lensreflex camera) image sequence to detect pre-failure events, while a combined analysis tool used the surface velocity fields and deformation areas based on fast HSCS (high-speed stereocamera system) stereo image sequences to reveal fast-changing landslide behavior during the short final failure. The introduced surface change detector uses the percentage of sliding block areas, percentage of changed features, and average speeds. It successfully detected four pre-failure local collapse events and the final slope failure; the extent of surface changes reached its maximum to accumulate energy 1.5 seconds before the failure when the average speed of changed features achieved its peak of 0.8 m/s. The developed system achieved a position accuracy of 3.8 mm and a speed accuracy of 0.11 m/s. The analysis result demonstrated a time period of 66 minutes before the failure which is confirmed by significant signals from both imaging and contact sensors and is important for landslide early warning. A field implementation scheme in western China will be designed and realized in the near future.
