Full textHyperspectral remote sensing has been used successfully to identify and map abundances and compositional difference of mineral groups and single mineral phases. This research will toward developing a 3D mineral mapping system that integrate surface (airborne and satellite) and subsurface (drill core) hyperspectral remote sensing data and carries it into quantitative mineral systems analysis. The main content and result is introduced as follows:- For Surface mineralogy mapping, we have developed and optimized the processing methods for accurate, seamless mineral measurements using Airborne and Satellite hyperspectral image. This requires solutions for unmixing background effects from target minerals to leave residual scaled mineral abundances equivalent to vegetation-free pixels. Another science challenge is to improve the atmospheric correction. Also Hapke BRDF model is used on the study in the linear and nonlinear mineral spectral mixing models.- For the subsurface mineralogy mapping, we have developed Field Imaging Spectrometer System (FISS) and Drill Core Logging for the subsurface mineralogy mapping, the Key science challenges will be establishing the accuracy of derived mineral products through associated laboratory analysis, including investigations from SWIR into the thermal infrared for measuring minerals.- The 3D mineral maps derived from hyperspectral methods can distinctly improve our understanding of mineral system. We use GIS system integrating surface and subsurface mineralogy mapping, with 3D mineral models for demonstration exploitation of economic mineral deposits in test site

Full textSpectroscopy in the visible-Near infrared (Vis-Nir) in combination with chemometry (As Partial Least Squares Regression (PLSR)) constitutes a promising tool to quantify various soil properties. Four analytical and soil spectral data bases have been constituted. The first corresponds to 22 artificial samples. The second and the third are two regional bases, respectively compounds of 125 samples from the temperate region of Brittany and 89 samples, collected in three distinct sites of the same arid region of the Djerid. The fourth is a compound of 144 samples collected on a given site of the Djerid region (580 ha). With the first base, we have : i) studied qualitatively, the influence of organic carbon and total iron contents on the spectral behavior then predicted their contents ii) studied the performance variation of the PLSR models according to the calibration set variation. The Brittany base has been analyzed for the organic carbon (CO), the totalnitrogen (Ntot), the pH, the Cation Exchange Capacity (CEC), the total ioron (Fetot) and coarses sand (SG)). Then while using the Principal Compotent Analysis (PCA), as selection procedure of calibration and prediction samples, we calibrated the regional 10 physico-chemical properties models and identified, for each property, which of the spectral ranges : combined Vis-NIR, Vis or NIR, offers the best prediction. The third basis served to study for the total carbon (Ctot) and the electric conductivity (EC), the effect of the calibration mode “specific site” versus” “regional” on the prediction.

Full textThe thesis works have contributed to improve the surface soi! moisture estimates and the root-zone soil moisture estimates on the Sahel band in West Africa. The first part was dedicated to assess the ability of different algorithms to estimate soi! moisture based on satellite measurements in thermal infrared spectrum. Ln the second part, a method was developed in order to obtain a soi! moisture mapping at high temporal resolution « 3h) based on two satellite products: a satellite-based rainfall product and dai!y passive microwave measurements sensitive to soi! moisture. Ln a third part, an assessment of the reliability and robustness of the methodology has been proposed. Finally, a semi-empirical method was used to produce root-zone soil moi sture maps (0-1 m) over the Sahel region. Ground-based soi! moisture measurements obtained at three sites in Mali, Niger and Benin during the AMMA pro gram were used to assess the quality of estimates of near-surface and root-zone soil moi sture at each stage of this work. The results show that an estimate of the surface soi! moisture is possible with an accuracy of less than 3% vol. Over the Sahel band. The error is about 5% vol. Over the Sudanian zone (Benin). The accuracy is identical for the root-zone soi! moi sture estimate. Finally, the developed method allows at the same time to correct satellite-based rainfall products and notably the overestimation of the annual accumulation and the number of rain events of the three rainfall satellite products used in this work

Full textHyperspectral sensors are passive Earth-looking systems providing, for each pixel of the image, a spectrum in the spectral range 0. 4-2. 5 micrometers at 10 nm intervals with a typical spatial resolution of a few meters. In this study, we adress the ill-posed problem of the joint inversion of atmospheric gas concentrations and equivalent ground reflectance (excluding spectral mixing and BRDF). Existing methods (e. G. , N/W, CIBR, APDA) allow the measurement of atmospheric water vapor content with a 5-6% rms typical accuracy and are mainly limited by a partially empirical approach. The study of the radiative transfer function and sensors' characteristics yielded the development of a method named JRGE (Joint Reflectance and Gas Estimator), which takes into account all the physical assumptions of the problem. This method provides a comprehensive mathematical framework based on a ground reflectance spline model and estimates variations in concentrations (relatively to a standard atmosphere model) of a predefined set of gases contained in a plume. An iterative version of the method, which allows the retrieval of total column abundances, is presented and named IJRGE (Iterative Joint Reflectance and Gas Estimator). Validations on simulated and field data (AVIRIS and HyMap) show that the proposed method yields a 2-2. 5 enhancement factor in comparison with existing methods. Further developments, including the analysis of aerosols and sensors' calibration (e. G. , spectral shift), should thus allow the monitoring of numerous geophysical phenomena with relatively low gas emission (e. G. , industrial pollution, forest fires, volcanoes)

Full textIn intensive agricultural regions, winter vegetation covering is a key indicator of water transfer processes. Its prediction can help local decision making for restoring water quality. The objective of this work is to develop a reproducible method to predict the land cover distribution for the following winter season for the two hypotheses "Bare soils" and "Covered soils". The selected modelling approach is based on an expert model using the Dempster-Shafer rule. Results are ambivalent according to the studied hypothesis. The prediction scores are good at the watershed scale but present limits for allocating the land class at a field scale, especially for the "Bare soils" class. The Dezert-Smarandache theory is then applied and increases the prediction scores for the "Bare soils" class. The reproductibility of the modelling approach is then evaluated in applying the model on another study site. The "Bare soils" class remains well evaluated with both fusion rules, but the spatial allocation of the land class at a field scale is still not well managed, that indicates the need to integrate new sources of information in the model to better predict the future land allocation
