Determination of Shoreline Position in the Dayyer Area in the Persian Gulf Using Landsat Satellite Data

Identification of shoreline position and mapping are critical for safe navigation¡ coastal resource management¡ coastal environmental protection and sustainable coastal development. Nowadays¡ application of satellite data is the newest and most economical method for this purpose. In this study¡ satellite data and object-oriented technique are used to determine position of shoreline and to provide shoreline map. The study area is located at the Bord-khun in the Bushehr province. An image provided by TM sensor of Landsat satellite for the study area in 2012 was used for shoreline mapping in this area. At first¡ geometric and radiometric corrections were performed on the image. Then the study area was classified by object-oriented method and map of shoreline was provided. Finally¡ Kappa coefficient and overall accuracy were used to assess accuracy of applied classification. Evaluation results indicate the high accuracy of this method for shoreline mapping.
