[Termes IGN] tsunamiRésumé : (Auteur) The massive 26 December 2004 earthquake and tsunami affected a large geographic region in the Indian Ocean basin, hitting Indonesia's Aceh province on the island of Sumatra particularly hard. In this study, tsunami inundation distances and run-up elevations on the NW Sumatran coast are assessed at a regional scale using remotely sensed data (ASTER, QuickBird and SRTM). Using satellite data in disaster zones allows tsunami scientists to access data in difficult areas (logistically and politically), along with the other benefits that such data has to offer (e.g. spectral and spatial). Field work rapidly following the tsunami allowed the collection of samples, elevation data and other information through interviews with survivors that validated the remotely sensed observations. Median run-up elevations extracted from SRTM and ASTER generated digital elevation models (DEMs) for the Banda Aceh area were 16 m and 9.7 m above sea level respectively, and field measurements averaged 9 m. In Meulaboh, median run-up elevations were 9 m (SRTM) and 6.6 m (ASTER) which are close to the 10-15 m range determined in the field. Run-up elevations at Jantang have a bimodal distribution with peaks that correspond to inundation limits in the floodplains (~10 m in both the SRTM and ASTER data) and cliffs (32 m in the ASTER and less well-defined in the SRTM data). Slope maps generated from SRTM and ASTER DEMs show that the inundation limit rarely exceeds slopes of 4°. Using the Aceh area as a control, SRTM and ASTER data and the range of possible products derived from them is here taken as potential suitable tool for computer inundation models that aid in evacuation planning.

[Termes IGN] tsunamiRésumé : (Auteur) The Sumatra earthquake struck South Asia on 26 December 2004 and triggered monstrous waves that turned into a tsunami hitting the ocean regions and caused the most severe natural disaster of recent decades. The devastating earthquake and tsunami changed the landscape of coastal areas in many countries around the whole Indian Ocean region. To provide real-time information for rescue and rehabilitation plans, satellite images were applied to monitor and evaluate the damage over several devastated spots. The FORMOSAT-2 satellite, which was launched on 21 May 2004 and operated by the National Space Organization, Taiwan, is uniquely designed to take timely and low-cost black and white images daily with a resolution of 2 m and colour images of 8-m resolution. FORMOSAT-2 is expected to have many useful applications, such as natural-disaster evaluation, land-usage analysis, environmental monitoring, and coastal search and rescue. FORMOSAT-2 successfully acquired several post-tsunami images of the hazardous areas, both Puhket, Thailand and Banda Aceh, Indonesia on 28 December. A series of FORMOSAT-2 satellite images were processed by geometric and radiometric correction, haze reduction, image enhancement, feature extraction, image classification, and image fusion to assess the damage over those devastated areas. FORMOSAT-2 satellite images with a high-temporal resolution and high-spatial resolution were proved to be an efficient and useful information source for decision-makers to make rescue and recovery plans, especially for some isolated islands hard to reach in time.

[Termes IGN] teneur en eau de la végétationRésumé : (Auteur) This paper evaluated the capacity of SPOT VEGETATION time-series to monitor herbaceous fuel moisture content (FMC) in order to improve fire risk assessment in the savanna ecosystem of Kruger National Park in South Africa. In situ herbaceous FMC data were used to assess the Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), Vegetation Dryness Index (VDI), Improved VDI (IVDI), and Accumulated Relative NDVI Decrement (ARND) during the dry season. The effect of increasing amounts of dead vegetation on the monitoring capacity of derived indices was studied by sampling mixed live and dead FMC. The IVDI was proposed as an improvement of the VDI to monitor herbaceous FMC during the dry season. The IVDI is derived by replacing NDVI with the integrated Relative Vegetation Index (iRVI), as an approximation of yearly herbaceous biomass, when analyzing the 2-dimensional space with NDWI. It was shown that the iRVI offered more information than the NDVI in combination with NDWI to monitor FMC. The VDI and IVDI exhibited a significant relation to FMC with R2 of 0.25 and 0.73, respectively. The NDWI, however, correlated best with FMC (R2 = 0.75), while the correlation of ARND and FMC was weaker (R2 = 0.60) than that found for NDVI, NDWI, and IVDI. The use of in situ herbaceous FMC consequently indicated that NDWI is appropriate as spatio-temporal information source of herbaceous FMC variation which can be used to optimize fire risk and behavior assessment for fire management in savanna ecosystems.

[Termes IGN] Union EuropéenneRésumé : (Auteur) Initiative européenne lancée en 1998, GMES (Global Monitoring for Environment and Security) a pour mission d'offrir à l'Europe de nouveaux moyens pour préserver son environnement et sa sécurité. Même si GMES n'est pas véritablement un programme, c'est une étiquette qui a donné une visibilité mondiale à toute une série de travaux de recherche et de développement d'applications liées à la télédétection. GMES doit maintenant passer en phase opérationnelle, mais ce n'est pas facile à organiser.

[Termes IGN] sol salinRésumé : (Auteur) Landsat images supply significant information on the different aspects of the physical environment necessary to determine the distribution of salty soils. This work centres on the La Mancha area (Central Spain) which, due to its flat topography, exhibits ideal conditions to show surface and groundwater movement, as well as sediment distribution. Combination of these factors is essential for development. The main goal of this study is to derive information on the distribution of salt-affected soils, as well as the area subject to flood risk. Multitemporal Landsat TM images selected from the 1990s have been used for this purpose. TM images are useful for delineation of mesozoic sediments rich in salts and/or areas with high humidity content. These images have been geo-referenced to the UTM coordinate system and have been digitally enhanced. Principal components, NDVI and supervised classification were computed. Therefore, it is quite possible to predict with a high degree of probability the development of saline soils, but their precise classification is not always possible, owing to the fact that they are usually associated with other soil groups: calcisols, regosols, luvisols and kastanozems. Salt-affected soils have been found to be associated with clayish mesozoic sediments, hollows, flood plain area and subsurface and groundwater movements. Complementary fieldwork is necessary in order to confirm digital values.
