Contribution to the study of the wetlands of the coastal wind mantle of The Abalario Donana AHS images

Abstract:

High spectral- resolution AHS data have been collected over the Manto Eolico Litoral El Abalario-Donana (MEL) within the nature reserve of Donana, a Ramsar wetland, which constitutes one of the largest and most important remaining wetlands in Europe. The MEL is located in the eolic mantle of the Huelva coastal plain and holds a large number of permanent and temporal shallow marsh lagoons. Natural vegetation is mainly composed of different types of shrub communities, whose distribution depends on their position with regard to the phreatic water table depth of the Almonte- Marismas aquifer. The AHS system is a new 80- band airborne hyperspectral scanner covering the visible through long wave thermal IR. Data were collected during three flight campaigns in spring and early fall 2004 and early fall 2005. Atmospheric correction and in situ spectral reflectance measurements have been applied and the …
