This has led to the Soil Moisture and Ocean Salinity (SMOS) mission, a European Space Agency (ESA) Earth Explorer Opportunity mission. SMOS has the objective to observe soil moisture over land and sea surface salinity over sea, both key parameters for atmospheric, oceanographic and hydrological predictive models. In preparation of SMOS, the EuroSTARRS airborne campaign was carried out in November 2001. Multi-angular measurements of the surface brightness temperature at L-band (1.4GHz) at vertical polarization were acquired by the 'Salinity Temperature and Roughness Remote Scanner' (STARRS) radiometer from the Naval Research Laboratory (NRL, USA) over several sites in Southern France, the Pyrenees and Eastern Spain. The chosen sites represent specific land conditions and vegetation canopies where microwave surface emission models need further investigation, and include: dense forests, shrubs and scrubland, mixed areas of different vegetation covers and areas with variable topography. This paper gives an overview of the experiment, including a discussion of the objectives, description of the sites, details of the microwave measurements and some first results of the campaign. First, a principal component analysis of the forest brightness temperature measured at different configurations illustrates the sensitivity of brightness temperature to biomass conditions for coniferous trees. Then, the microwave signature of the vegetation covers considered in this study-coniferous forest at Les Landes (France), mixed deciduous/coniferous stands at the Agre forest (France), shrubland, vineyards and orchards at the Valencia site (Spain) - is illustrated, in particular as regards to the dependance of the L-band emissivity to biomass conditions.

[Termes IGN] turbidité océaniqueRésumé : (Auteur) New photobathymetry and water quality software is described here that utilizes subpixel analysis software (Subpixel Classifier) with an autonomous image calibration procedure and analytic retrieval algorithm to simultaneously retrieve and report bottom depth and the concentrations of suspended chlorophyll, suspended sediments, and colored dissolved organic carbon on a perpixel basis from four-band multispectral image data. From the derived composition, the QSC2 (Quantitative Shoreline Characterization, Version 2.0) software also computes and reports water column visibility parameters (vertical and horizontal subsurface sighting ranges and turbidity, each at four wavelength band passes, plus Secchi depth as a scalar) as well as depth and turbidity confidence. Qsc2 compensates for the effects of the atmosphere, sun and sky reflections from the water surface, subpixel contributions from exposed land, and variations in the bottom material properties. All information is derived automatically from the pixel data alone. The performance of the Qsc2 software was demonstrated using a four-band Ikonos image of Plymouth, Massachusetts. Accuracies of the image-derived compositions, water clarity, and depths were assessed using field and laboratory measurements for eight representative lakes in the scene. The means of the differences of the field-measured and image-derived suspended chlorophyll and colored dissolved organic carbon concentrations for the eight lakes were 1.82 ug/l and 4.34 mgC/1, respectively. The image-derived concentrations of suspended sediments were all below the threshold of detection for the field samples (5 mg/1), in agreement with the field data. The mean of the differences between field-measured and image-derived Secchi depths was 0.76 m. The mean depth difference was 0.57 m.

[Termes IGN] reconstruction 3DIndex. décimale : 33.30 Photogrammétrie numérique Résumé : (Auteur) A novel System for automatic building reconstruction from multiple aerial images is presented. Compared to previous works, this approach uses a very generic modeling of buildings as polyhedral shapes with no overhang, in which external knowledge is introduced through constraints on primitives. Using planes as base primitives, the algorithm builds up an arrangement of planes from which a 3D graph of facets is deduced. In a so-called "compatibility graph" where the nodes are the initial facets of the 3D graph and edges between two nodes state that both facets belong to at least one common hypothesis of building, it is shown that maximal cliques supply all the hypotheses of buildings that can be deduced from the arrangement of planes. Among these hypotheses the choice is done through a bayesian formulation that balance data adequacy and caricature needs. Results are provided on real images and show the validity of the approach that remains very generic on the contrary to model-based methods while bringing extemal architectural information through geometric constraints, which generally lacks in data-driven algorithms.

[Termes IGN] turbidité des eauxRésumé : (Auteur) Many aquatic ecosystems in the United States and worldwide are impaired by the over-enrichment of waters by nutrients. In advanced stages, the process of eutrophication can cause harmful algae blooms. This research retrieved the concentrations of suspended chlorophyll (Chl), suspended minerals (SM), colored dissolved organic carbon (DOC), and turbidity (total attenuation) from AVIRIS imagery of a severely overenriched waterway in North Carolina, and evaluated if these parameters could be used as indicators of conditions leading to algae blooms. A digital image processing algorithm called Qsc1 (Quantitative Shoreline Characterization, Version 1.0) was used. The retrieved water quality parameter values were tested by statistical comparisons to field measurements made at the time of the AVIRIS data collection. Applying Qsc1 to AVIRIS imagery resulted in measurements of Chl that correlated well with field measurements (r = 0.84). Problems with field sampling prevented the assessment of retrieveSM and Doc. The statistical correlation analysis indicated that, for comparison to remotely sensed data, field measurements in the steadily flowing Neuse River must be collected within two hours of the imagery. Thematic maps of each water quality parameter were generated from the imagery and evaluated. The maps of Chl showed spatial patterns consistent with the field data and circulation of the river, and indicated potential point and non-point sources. Statistical and principle component analyses were used to assess whether the AVIRIS water quality measurements were directly or indirectly related to parameters and conditions indicative of nutrient loading and algae blooms that were measured in the field. The AVIRIS measurements were used to create a new index of eutrophication, the Algae Production Potential Index (Appi), for the purpose of mapping where conditions of high nutrient loading and potential algae blooms exist. The index uses direct measurements of Chl, Doc, and Sm (as a surrogate for phosphate). These measurements are combined in a Gis model based on ecological relationships. Although not field verified, the APPI map shows patterns of algae bloom conditions that are similar in size, scale, and location to previous blooms in the Neuse.
