The main aim of these lectures is to illustrate different approaches for the retrieval of biophysical parameters with a specific focus on snow and glaciers, by combining optical and radar satellite images.
Prerequisiti
Basic knowledge about physics (electromagnetic waves), remote sensing sensors (passive and active sensors) and data (digital numbers, processing levels).
Metodi didattici
Lectures and interactive discussion and experiments using an open access software.
Verifica Apprendimento
The students will be asked to discuss a case study and provide a report that will be evaluated.
Testi
The slides used by the teacher will be provided, together with a list of relevant books and literature papers.
