[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] 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.

[Termes IGN] phaseRésumé : (Auteur) Synthetic aperture radar interferometry (InSAR) is an alternative to conventional stereoscopic SAR for extracting relative or absolute terrain elevation information. However, for different InSAR data-sets, the auxiliary parameters are different, which introduces differences in the SAR interferometry rigorous sensor model (RSM). The Rational Polynomial Coefficient (RPC) model is a generalised sensor model which makes full use of the auxiliary parameters of the satellite images, and the coefficients of the model are then solved by fitting the model to the RSM. Some work has been carried out previously to validate its substitutability for the SAR RSM, which is based on the Range–Doppler equations. Further, this paper aims to prove that the RPC model can also be used as a replacement for the InSAR phase equation and can be widely applied on different types of InSAR data-sets. Based on numerous tests, the modelling error of the RPC is analysed. This study found that the RPC model is suitable for InSAR data-sets and it can be used as a replacement for the phase equation.

[Termes IGN] traitement de données localiséesRésumé : (Auteur) Immediately following the 12 January 2010 earthquake in Haiti, a disaster response team from Rochester Institute of Technology, ImageCat Inc., and Kucera Internationa!, funded by the Global Facility for Disaster Reduction and Recovery group of the World Bank, collected 0.15 m airborne imagery and two points/m2 lidar data for 650 km2 over a period of seven days. Data were transferred to Rochester, New York for processing at rates that approached 400 Mb/s using Internet2, orthorectified with a 24-hour turnaround, and distributed to response agencies through file or disk transfer. A unique response effort, dubbed the Global Earth Observation - Catastrophe Assessment Network (geo-can) and headed by ImageCat, utilized over 600 experts from 23 different countries to generate rapid turnaround damage assessment products. This paper highlights the airborne data collection, transfer, processing, and product development effort, which arguably has raised the bar in terms of response to large-scale disasters.

[Termes IGN] spatiocarteRésumé : (Auteur) The paper reports on the activity of the Center for Satellite based Crisis Information (ZKI) of the German Aerospace Center (dim) in the aftermath of the devastating earthquake in Port-au-Prince, Haiti on 12 January 2010. DLR/ZKI closely coordinated with the European Global Monitoring for Environment and Security (GMES) program and the International Charter Space and Major Disasters, AH dlh/zki damage maps are based on a specific analysis approach, including preprocessing procedures and visual interpretation on a grid-basis. As the satellite-based mapping response globally was so extensive for this event, problems resulting from the large number and inconsistency of satellite maps generated internationally are addressed. In order to avoid this kind of "mapping challenge" in future the setting-up of an international working group to elaborate global guidelines and cooperation procedures for better coherence of international satellite rapid mapping efforts for extreme events such as the Haiti earthquake is suggested.
