[Termes IGN] rétrodiffusionRésumé : (Auteur) It is sometimes difficult to monitor the water level of reservoirs with a sloping bank – such as many lakes and earth-dam embankment – using terrestrial techniques or airborne instruments. A proposed alternative is a new technique using a terrestrial near-infrared Lidar mounted with a large incidence angle (at least between 40° and 70°). This technique assumes that the Lidar can detect the (sub-)surface of a water body provided that it contains enough suspended particles to backscatter the light emitted by the instrument to its detector. Tests performed with a commercial Lidar show that the technique can be used to estimate the water level of a reservoir with moderate accuracy (within 10.05 m [p = 0.95]) when the water is very turbid (Secchi depth Numéro de notice : A2011-521 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Article nature-HAL : ArtAvecCL-RevueIntern DOI : 10.1016/j.isprsjprs.2011.01.009 En ligne : https://doi.org/10.1016/j.isprsjprs.2011.01.009 Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=31415

[Termes IGN] zone polaireRésumé : (Auteur) The in situ measurements of electron contents from GRACE K-band (dual-frequency) ranging system and CHAMP planar Langmuir probe were used to validate the international reference ionosphere (IRI) models. The comparison using measurements from year 2003 to 2007 shows a general agreement between data and the model outputs. The improvement in the newer IRI model (IRI-2007) is evident with the measurements from the GRACE satellites orbiting at the higher altitude. We present the comparison between the models and data comprehensively for various cases in solar activity, local time, season, and latitude. The IRI models do not well predict the electron density in the years 2006 and later, when the solar activity is extremely low. The IRI models generally overestimate the electron density during local winter while they underestimate during local summer. In the equatorial region, the large difference at local sunrise lasts for all years and all seasons. The IRI models do not perform well in predicting the anomaly in the polar region such as the Weddell Sea Anomaly. These discrepancies are likely due to smoothed (12-month averaged) solar activity indices used in the IRI models and due to insufficient spherical harmonic representation not able to capture small spatial scales. In near future, further improvement on the IRI models is expected by assimilating those in situ satellite data by implementing higher resolution (spatial and temporal) parameterizations.

Dans cette étude, il est question de les cartographier dans la région des Lacs située au centre de la Côte d'Ivoire. Cette cartographie est le point de départ d'une série d'études sur ces sols devant aboutir à leur évaluation en vue de leur éventuelle mise en valeur agricole. La méthode de cartographie adoptée est l'approche du Spectral Angle Mapper (SAM), méthode basée sur la similarité spectrale. Ainsi, nous avons procédé, à partir de l'image ASTER utilisée, à l'extraction d'un nombre limité de signatures prototypes pouvant caractériser et expliquer la variabilité spectrale dans l'image. La sélection de ces signatures spectrales a été faite de façon automatique par l'approche de l'Indice de Pureté du Pixel ou PPI (Pixel Purity Index). Pour déterminer la contribution spécifique de l'approche du SAM à la cartographie des zones humides, nous avons procédé à une évaluation comparative des résultats obtenus par le SAM avec ceux obtenus par la méthode du Maximum de Vraisemblance (notre référence) qui est perçue en général comme étant robuste et fiable. Ces deux classifications ont été réalisées sur la base des mêmes parcelles d'entraînement et d'apprentissage. Les critères de précision globale et de coefficient de Kappa calculés pour évaluer les résultats obtenus montrent un avantage en faveur de la méthode du SAM. En effet, cette dernière a obtenu une précision globale et un coefficient de Kappa respectivement de 95,68 % et 0,94 contre dans le même ordre, 88,43 % et 0,88 pour la méthode du Maximum de Vraisemblance. Aussi, le SAM s'est-il illustré par les meilleures précisions en ce qui concerne l'inventaire des différentes composantes des zones humides.

[Termes IGN] zone homogèneRésumé : (Auteur) Harnessing the radiometric information provided by photogrammetric flights could be useful in increasing the thematic applications of aerial images. The aim of this paper is to improve relative and absolute homogenization in aerial images by applying atmospheric correction and treatment of bidirectional effects. We propose combining remote sensing methodologies based on radiative transfer models and photogrammetry models, taking into account the three-dimensional geometry of the images (external orientation and Digital Elevation Model). The photogrammetric flight was done with a Z/I Digital Mapping Camera (DMC) with a Ground Sample Distance (GSD) of 45 cm. Spectral field data were acquired by defining radiometric control points in order to apply atmospheric correction models, obtaining calibration parameters from the camera and surface reflectance images. Kernel-driven models were applied to correct the anisotropy caused by the bidirectional reflectance distribution function (BRDF) of surfaces viewed under large observation angles with constant illumination, using the overlapping area between images and the establishment of radiometric tie points. Two case studies were used: 8-bit images with applied Lookup Tables (LUTs) resulting from the conventional photogrammetric workflow for BRDF studies and original 12-bit images (Low Resolution Color, LRC) for the correction of atmospheric and bidirectional effects. The proposed methodology shows promising results in the different phases of the process. The geometric kernel that shows the best performance is the Lidense kernel. The homogenization factor in 8-bit images ranged from 6% to 25% relative to the range of digital numbers (0–255), and from 18% to 35% relative to levels of reflectance (0–100) in the 12-bit images, representing a relative improvement of approximately 1–30%, depending on the band analyzed.

[Termes IGN] ressources en eauRésumé : (Auteur) Given that water resources are scarce and are strained by competing demands, it has become crucial to develop and improve techniques to observe the temporal and spatial variations in the inland water volume. Due to the lack of data and the heterogeneity of water level stations, remote sensing, and especially altimetry from space, appear as complementary techniques for water level monitoring. In addition to spatial resolution and sampling rates in space or time, one of the most relevant criteria for satellite altimetry on inland water is the accuracy of the elevation data. Here, the accuracy of ICESat LIDAR altimetry product is assessed over the Great Lakes in North America. The accuracy assessment method used in this paper emphasizes on autocorrelation in high temporal frequency ICESat measurements. It also considers uncertainties resulting from both in situ lake level reference data. A probabilistic upscaling process was developed. This process is based on several successive ICESat shots averaged in a spatial transect accounting for autocorrelation between successive shots. The method also applies pre-processing of the ICESat data with saturation correction of ICESat waveforms, spatial filtering to avoid measurement disturbance from the land–water transition effects on waveform saturation and data selection to avoid trends in water elevations across space. Initially this paper analyzes 237 collected ICESat transects, consistent with the available hydrometric ground stations for four of the Great Lakes. By adapting a geostatistical framework, a high frequency autocorrelation between successive shot elevation values was observed and then modeled for 45% of the 237 transects. The modeled autocorrelation was therefore used to estimate water elevations at the transect scale and the resulting uncertainty for the 117 transects without trend. This uncertainty was 8 times greater than the usual computed uncertainty, when no temporal correlation is taken into account. This temporal correlation, corresponding to approximately 11 consecutive ICESat shots, could be linked to low transmitted ICESat GLAS energy and to poor weather conditions. Assuming Gaussian uncertainties for both reference data and ICESat data upscaled at the transect scale, we derived GLAS deviations statistics by averaging the results at station and lake scales. An overall bias of -4.6 cm (underestimation) and an overall standard deviation of 11.6 cm were computed for all lakes. Results demonstrated the relevance of taking autocorrelation into account in satellite data uncertainty assessment.
