Abstract

This paper considers the use of remotely-sensed data from high-spectral resolution imagers for the observation of Mediterranean land degradation and soil erosion. The Ardeche test site in France was selected as an experimental site. The GER Imaging Spectrometer (GERIS) was used to acquire imaging spectrometry data of the site, and radiometric measurements were taken on the ground. The results confirm that the second GERIS short-wave infrared spectrometer has the potential to detect absorption features of minerals such as phyllosilicates and carbonates. It can also detect combined lignin-cellulose absorption in dry plant material (mature grain crops) and "green canopies" that include large amounts of dry grass, leaf litter and bark. These detection capabilities are an important prerequisite for the remote-sensing-based characterisation of Mediterranean woodlands, which usually form inhomogeneous mixtures of green and dry vegetation and exposed soil or bedrock.
