Earth and Planetary Remote Sensing

Recommended Prerequisites

NA

Teaching Methods

Lectures are dedicated to the theory (physics) and some examples of applications from the literature. Practicals allow students to familiarize themselves with hyperspectral image processing through different applications (understanding and using spectral signatures, quantitative mapping, classification, spectral indices, etc.). Students then select a project among the proposed ones (Environmental Geology on Earth, mineral mapping on Earth, Mars, the Moon, Ice on Mars, etc.) and work by themselves, in small groups. Results are presented orally and in a report.

Learning Outcomes

At the end of the course, students will be able to

• understand what physico-chemical information can be extracted from imaging spectrometer data

acquired over Earth and other planets and moons of the solar system

• correct hyperspectral images from atmospheric effects using empirical and physical approaches

• extract quantitative information from hyperspectral images

• use hyperspectral images to map surface compositions

• understand how light propagates into the ocean

• understand how above-water reflectance can be used to quantitatively retrieve biogeophysical information on the main seawater colored constituents

Work Placement(s)
