Coastal Zone Management (CZM) involves the planning and organizing of development, controlling activities in the coastal zones, and preserving these areas for future generations. An important component of CZM is a computer-based Coastal Information System (CIS). This paper describes a CIS developed for the Koycegiz-Dalyan Specially Protected Area (SPA) in Turkey. The CIS was established within the framework of the International Mediterranean Project (IMP) which won the Henry Ford European Conservation Award (National Award (2 prize) 1998) on March 31, 1998. The project was supported by the European Space Agency (ESA). The importance and effectiveness of the ground truth and space-borne sensor data for environmental and resource management were also discussed.
