Using the Landsat Archive for the Monitoring of Mediterranean Coastal Wetlands: Examples from the GlobWetland-II Project
Coastal wetlands in the Mediterranean have undergone considerable land use and land cover changes in recent decades, by way of urban growth and increasing tourism infrastructure. The GlobWetland-II project makes use of the 35 years of Landsat archives for a basic identification and delineation of wetlands during 1975, 1990, and 2005.
