[Termes IGN] spectroradiomètreRésumé : (Auteur) The main troubles affecting the application of remote sensing are connected with the radiometric calibration of the sensor signal as well as with the physical parameters to be used for the radiative transfer modelling through the atmosphere. In order to overcome these problems, we are developing two new instruments to be used for in-field measurements devoted to the validation of remotely sensed hyperspectral images. The main instrument is a solar spectro-irradiometer, operated in the imaging-spectrometer mode, that samples the impinging irradiance with 7 nm of spectral resolution and a digitalisation accuracy of 10 bit. The 256 independent samples held in the measured spectrum are acquired with a sampling step of about 3.0 nm and cover the range from 200 nm up to 950 nm of wavelength. From this original instrument we have also derived a spectro-radiometer having similar spectral characteristics. In this paper, we discuss the development of the main common spectrometer and describe the experimental activity carried out for its calibration. Preliminary experimental data are shown and thoroughly analysed.

[Termes IGN] télédétection aérienneRésumé : (Auteur) We have investigated the problem of fire recognition and management assuming that the fire may produce noticeable effects in almost the entire optical spectral range (from the visible until the thermal infrared). Accordingly, we have chosen to exploit the application to the concerned problem of airborne, high resolution hyperspectral sensors that provide the user with a large amount of information about the spectral properties of the imaged target. The main problems addressed by this work are the firefront and burnedarea recognition and the extraction of information useful for the management of the burned area. The paper shows data gathered by the sensor MIVIS over the fire, the data processing result and is completed with a brief theoretical discussion of the involved topics. Some hints are given about the diagnostic capabilities of other hyperspectral devices.
