[Termes IGN] qualité des eauxRésumé : (Auteur) The applicability of image calibration to likevalues in mapping water quality parameters from multitemporal images is explored. Six sets of water samples were collected at satellite overpasses over Moreton Bay, Brisbane, Australia. Analysis of these samples reveals that waters in this shallow bay are mostly TSS dominated, even though they are occasionally dominated by chlorophyll as well. Three of the images were calibrated to a reference image based on invariant targets. Predictive models constructed from the reference image were applied to estimating total suspended sediment (TSS) and Secchi depth from another image at a discrepancy of around 35 percent. Application of the predictive model for TSS concentration to another image acquired at a time of different water types resulted in a discrepancy of 152 percent. Therefore, image calibration to likevalues could be used to reliably map certain water quality parameters from multitemporal TM images so long as the water type under study remains unchanged. This method is limited in that the mapped results could be rather inaccurate if the water type under study has changed considerably. Thus, the approach needs to be refined in shallow water from multitemporal satellite imagery.

[Termes IGN] modélisation géométrique de prise de vueRésumé : (Auteur) The Airborne Three-Line-Scanner (TLS) imaging system has provided proof of the concept of stereo and multispectral mapping using the pushbroom mode because frame digital imaging systems with comparable coverage and resolution have not been available and are not likely to be available in the future. A prototype of the TLS system, the STARIMAGER, was developed jointly in 2000 by the STARLABO Corporation of japan and the University of Tokyo and is introduced in this paper. A laboratory method and algorithm to evaluate the optical characteristics of STARIMAGER are presented. The principle is to measure the object-space angles of a sufficient number of CCD elements in two directions as seen through the optics. These angular measurements reflect the real camera geometry of both the optics and the GCD arrays. A mathematical model based on the central perspective projection has been constructed to estimate the focal length, principle point, and lens distortion of the optics and the alignment errors of the CCD sensors in the focal plane. These calibration parameters have been used in several real test flights, and ground point determination accuracies from 0,03 to 0.08-m (0.5- to 1.5-pixels) in planimetry and from 0.06- to 0.15-m (1.2 to 3-pixels) in elevation from a flying height of 500 m were attained.

[Termes IGN] traitement d'imageRésumé : (Auteur) Previous studies have shown the possibility of using European Remote Sensing/Synthetic Aperture Radar (ERS/SAR) data to monitor surface soil moisture from space. The linear relationships between soil moisture and the SAR signal have been derived empirically and, thus, were a priori specific to the considered watershed. In order to overcome this limit, this study focused on two objectives. The first one was to validate over two years of data the empirical sensitivity of the radar signal to soil moisture, in the case of three agricultural watersheds with different soil compositions and land cover uses. The slope of the observed relationship was very consistent. Conversely, the offset could change, making the soil moisture retrieval only relative (and not absolute). The second one was to propose an "operational" methodology for soil moisture monitoring based on ERS/SAR data. The implementation of this methodology is based on two steps : the calibration period and the operational period. During the calibration period, ground truth campaigns are performed to measure vegetation parameters (to correct the SAR signal from the vegetation effect), and the ERS/SAR data is processed only once a field land cover map is established. In contrast, during the operational period, no vegetation field campaigns are performed, and the images are processed as soon as they are available. The results confirm the relevance of this operational methodology, since no loss of performance (in soil moisture retrieval) is observed between the calibration and operational periods.
