[Termes IGN] transformation en ondelettesRésumé : (Auteur) This paper presents a novel approach to change detection in multitemporal synthetic aperture radar (SAR) images. The proposed approach exploits a wavelet-based multiscale decomposition of the log-ratio image (obtained by a comparison of the original multitemporal data) aimed at achieving different scales (levels) of representation of the change signal. Each scale is characterized by a different tradeoff between speckle reduction and preservation of geometrical details. For each pixel, a subset of reliable scales is identified on the basis of a local statistic measure applied to scale-dependent log-ratio images. The final change detection result is obtained according to an adaptive scale-driven fusion algorithm. Experimental results obtained on multitemporal SAR images acquired by the ERS-1 satellite confirm the effectiveness of the proposed approach.

[Termes IGN] visualisationRésumé : (Auteur) The currency of geospatial data is critical for the analysis and visualization of the environment. Out-of-date geospatial data have historical value, but if the data are used to analyze current events, the results could be contaminated to a point where they are incorrect or completely wrong. There are two possible solutions to the problem of outdated geospatial data. The first solution is to collect the data again and then generate new maps or any other type of geospatial data visualization. This approach is very costly, especially for countries that are of medium to large size. The second solution is the identification of changes to the landscape and the replacement of these changes by new data. This paper presents the theoretical framework for updating geospatial data. Two major issues are discussed: (1) how to detect changes in the data, and (2) how to correct the changes.

[Termes IGN] voisinage (relation topologique)Résumé : (Auteur) This study introduces a change detection model based on Neighborhood Correlation Image (NCI) logic. It is based on the fact that the sail-, geographic area (e.g., a 3 x 3 pixel window) on two dates of imagery will tend to be highly correlated if little change has occurred, an uncorrelated when change occurs. Computing the piecewise correlation between two data sets provides valuable information regarding the location and numeric change value derived using contextual information within the specified neighborhood. Various neighborhood configuration (i.e., multi-level NCls) were explored in the study using high spatial resolution multispectral imagery: smaller neighborhood sizes provided some detailed change information (such as a new patios added to an existing building) at the cost of introducing some noise (such as change, shadows). Larger neighborhood sizes were useful for removing this noise but introduced some inaccurate change information (such as removing some linear feature changes). When combined with image classification using a machine learning decision tree (C5.0), classifications based on multi-level NCIs yielded superior results (e.g., using a 3-pixel circular radius neighborhood had a Kappa of 0.94), compared to the classification that did not incorporate NCIs (Kappa=0.86).

[Termes IGN] zone urbaineRésumé : (Auteur) Study of the detailed structure and ecological functioning of urban and peri-urban systems is intensifying due to increasing concentration of the human population into urban centers. Much of this increase is expected to occur in semiarid to arid cites. Data from new high spatial, temporal, and spectral resolution satellite-based sensors promise to increase our understanding of global urban ecological and climatic processes and improve city and land planning capabilities. Two of these sensors, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and the Moderate Resolution Imaging Spectroradiometer (MODIS), provide an opportunity to compare urban spatial structure (distribution and configuration of discrete land cover/land use classes on the landscape) with contemporaneous measurements of surface biophysical composition at a variety of spatial and temporal scales. Such combined measurements are useful for modeling changes to urban climate, hydrology, and biogeochemical cycles caused by modification of the landscape. We compare gridded landscape metrics derived from expert systern land cover classification of ASTER to corresponding MODIS NDVI data at scales of 250 m/pixel, 500 m/pixel, and 1 km/pixel in order to determine which of these scales is optimal for monitoring of urban biophysical processes and landscape structure change. Weak positive and negative correlations between NDVI and landscape structure were observed at all three spatial scales for the metrics Class Area, Mean Patch Size, Edge Density, and Interspersion/Juxtaposition Index.

[Termes IGN] zone humideRésumé : (Auteur) Les zones humides situées au coeur des marges semi-arides du domaine méditerranéen sont des milieux fragiles, sensibles aux variations introduites dans leurs bilans climatiques et/ou hydrologiques et particulièrement marquées par des pressions anthropiques accrues depuis les années 1960. En Anatolie centrale, la disparition rapide et récente des zones humides revêt de multiples facettes. L'objectif de cet article est de monter comment le traitement d'une série d'images satellitales multispectrales (LANDSAT TM et SPOT XS) permet de mettre en évidence d'une part, la vitesse des changements structurels au sein de la zone humide d'Akgol (i.e. contraction, fragmentation et mutations) à partir d'une analyse diachronique régressive (2000-1993-1987-1984) et, d'autre part, d'identifier la nature des transformations spatiales (i.e. ouverture de la roselière, progression de la steppe herbacée, etc.) à partir de classifications croisées. Ces résultats sont utiles à une meilleure compréhension de la sensibilité des marais aux dynamiques récentes des paysages centre-anatoliens.
