OVERVIEW

The couse covers the basic priciples of Remote Sensing such as the processing, enhancement and visualization of multispectral, hyperspectral and panchromatic data acquired with passive (optical) and active (radar) sensors. Applications are focussed, among the others, on geological studies on georesources, hazard and enviromment.

L'insegnamento tratta gli argomenti basilari del Telerilevamento come il processamento, il miglioramento e la visualizzazione di dati multispettrali, iperspettrali e pancromatici acquisiti con diversi sensori passivi (ottici) e attivi (radar) per applicazioni finalizzate a studi geologici, delle georisorse e dei rischi, ed in generale del territorio e dell’ambiente.

AIMS AND CONTENT

LEARNING OUTCOMES

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 i) geology; ii) geo-resources and geohazard; iii) territory and environment. The aim of the course is to provide the basic culture to be able to select, to process and to interpret the proper satellite images for specific geological and geoenvironmental applications. For this purpose, the course includes both theoretical lessons on the basic principles of remote sensing and lab exercises on the spectral, radiometric and geometric characteristics of several satellite images.

AIMS AND LEARNING OUTCOMES

At the end of the course the student will be able to properly select satellite images and to develop effective strategy of image processing and enhancemennt for specific geological and geo-environmental studies.

Specifically the student will be able to:

- identify, select and download remote sensing data from public and open databese (e.g. USGS, ESA, NASA);

- perform image processing (e.g. spectral enhancement, convolution filtering, spectral index, principal component analysis, color transforms, pan sharpening, change detection);

- multi-temporal analyses;

- prepare tematic maps and perform supervised and unsupervised classifications;

- apply geometric corrections and georeferencing; 

-radar image processing and interferometric analyses

PREREQUISITES

Basic knowledge in Mathematics, Physics, Geology, and carthography acquired during the undergraduate degree courses.

TEACHING METHODS

The course includes both lectures in the classroom and practical excercises at DISTAV computer labs  where open source software will be used to process free and public satellite image dataset. Attendance to all planned activities is strongly recommended.  Test exercises will be carried out for evaluating the ongoing assessment of class learning. Please refer to the specific AulaWeb application for teaching for any update.

Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Sara Ferrando (sara.ferrando@unige.it), the Department’s disability liaison.
