Determination of shore edge line is a very important part of coastal planning in order to provide sustainable development in coastal areas. City of Antalya (Turkey), being world-wide famous touristic location, has been undergoing intense infrastructure development in order to accommodate the demand. In order to provide guidance to such developments, in this study, shore edge line of Lara-Kundu (Antalya) region has been determined depending on geological, geomorphological and other natural conditions in accordance with the definitions given in Turkish Coastal Law (3621) No. 4. In the field, high tide-low tide water levels and shore edge line with corresponding coordinates have been determined using differential UPS with application of "real-time measurement" technique. The extent of natural vegetation, degree of compaction of sediments and topographic rises has been used as criteria for determination of shore edge line. In order to observe natural state of the coastal area before the constructions, to complete geomorphological map and to confirm the shore edge line determined in the field, high resolution Quickbird satellite images of 2002 and 2009 were used. Also, the extent of natural vegetation before the construction works was determined using normalized difference vegetation index (NDVI) approach. The result of the study shows that the shore edge line in the study area ranges between 25 m and 205 m starting from low tide water level.
