Monitoring the Changing Position of Coastlines Using Information Technologies, An Example of Tekirdag

Abstract

Urbanisation has been an important component of land use and land cover change, and its significance will undoubtedly continue to increase with the majority of the world population swarming into cities. Coastal areas are the most variable units on earth. Especially for the last 30 years, coastal areas of Turkey have been under tremendous repression mainly because of population explosion arising from the domestic and foreign tourism demands, and also settlements by holiday dwellers and industrial companies, highways constructed to overcome traffic problems, intentions to convert beaches to sand supplying quarries and the other applications. Determination of shoreline changes from satellite imageries which had taken at different times is important for sustainable shore development and planning. This paper introduces an efficient method to monitor coastline and coastal land use changes using aerial photos and satellite imagery covering the same geographical area and, examines changing causes with the help of geographic information system (GIS) and remote sensing (RS). In consequence of the studies, it is established that the 294 649 m(2) of the area were filled and that the circumferential length of this fill area is 7207 m.
