This work focuses on the evaluation of Aerosol Optical Thickness (AOT) in Mt. Etna volcano area starting fromthe analysis of MIVIS VIS images. MIVIS images and ancillary data (atmospheric profiles, photometric measurements,atmospheric infrared radiances, ... see more

The main objective of land remotely sensed images is to derive biological, chemical and physical parametersby inverting sample sets of spectral data. For the above aim hyperspectral scanners on airborne platform are apowerful remote sensing instrument for... see more

Sensor radiometric calibration is of great importance in computing physical values of radiance of the investigatedtargets, but often airborne scanners are not equipped with any in-flight radiometric calibration facility. Consequently,the radiometric calib... see more

To assess the suspended and dissolved matter in water in the visible and near infrared spectral regions it is necessaryto estimate with adequate accuracy the water leaving radiance. Consequently radiance measured by a remotesensor has to be corrected from... see more

Remotely sensed data, recorded by means of the MIVIS hyperspectral scanner in the framework of the researchactivity of the CNR Institutes IIA-LARA and IMAA, have been calibrated to reflectance values and then quantitativelycompared with ground data. A new... see more

In July 2001 an aerial survey with MIVIS (Multispectral Infrared and Visible Spectrometer) hyperspectral sensor andan in situ survey campaign were performed on Venice lagoon to map benthic macro-algae and sea phanerogams distribution.On MIVIS VIS spectral... see more

The use of airborne scanners involves geo-referencing problems, which are difficult because of the need to knowthe exact platform position and attitude for each scan line. The errors of the onboard navigation system are normallycorrected using ground cont... see more

Within the framework of the European MVRRS project (Mitigation of Volcanic Risk by Remote SensingTechniques), in June 1997 an airborne campaign was organised on Mt. Etna to study different characteristics ofthe volcanic plume emitted by the summit craters... see more

new experimental approach to land analysis has recently been developed, based on the integration of informationacquired on different scales; it enables the structure and the functionality of the vegetation in natural ecosystemsto be analysed. This researc... see more
