The course provides the basic knowledge for aquatic ecosystem mapping; it covers basic principles and physically based modelling for turning optical satellite data into bio-physical measurements. Specific lectures on the PRISMA mission will enable to familiarise with hyperspectral technology and related applications.
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 attend an interactive session with Q&A every day, plus a dedicated session in the last day of the courses. The evaluation will be based on their ability to reply and discuss the proposed topics.
Testi
The slides used by the teacher will be provided, together with a list of relevant books and literature papers.
