June 29, 9:30am-1:30pm CET - Mapping surface water bodies from space by Zoltan Vekerdy / Arno van Lieshout (ITC)
Summary
One of the most dynamic land cover types is water. It appears in several forms (oceans, lakes, rivers, wetlands and many more different bodies), with a wide variety of occurrences, sizes and dynamics. Regular mapping and monitoring of them are of vital importance for water and environmental management both in the case of its abundance as well as of its scarcity.
The course gives the theoretical background of surface water body mapping with optical and radar satellite images, covering the problems of identifying water cover, delineation of water boundaries, handling mixed occurrence of water, vegetation and soils, etc. In the practical exercise, the participants will monitor a selected inland lake (Lake Urmia, Iran) using satellite images.
