20402409 - REMOTE SENSING

The remote sensing course focuses on the main aspects related to the analysis of remotely sensed images acquired both with passive and active sensors. The analyses will be aimed to the study of geo-resources, of the territory, of the environment and of the tectonics. The aim of the course is to provide the basic culture in order to be able to select, to process and to interpret the proper satellite images for specific geological/environmental applications. for this purpose the course include both theoretical lessons on the basic principles of remote sensing and lab exercises on the spectral, radiometric and geometric characteristics of several satellite images
