This submitted project proposes an analysis of uncertainties of soil properties estimations obtained from VNIR/SWIR remote sensing data. The uncertainties affecting soil properties estimations will be analyzed in regard to:
– the acquisition conditions. The sensitivity of soil properties estimations, to the soil moisture, bare soil surface coverage… will be analyzed.
– the atmospheric correction models. The sensitivity of soil properties estimations to the atmospheric corrections software (ATREM, FLAASH, ATCOR…) will be analysed. And the sensitivity to the atmospheric correction parameters software (elevation of sensor, elevation of study area, ozone column…) will be also analysed.
To proceed, we will use a time-series of Sentinel-2 data and a time-series of HYPERION data, both acquired over our study area.
