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. The authors present results of wetland identification and delineation mapping from 1975 to 2002, for the test sites of the Menderes Delta and Güllük Bay.
