Abstract :
Managing coastal zones needs accurate and updated information about coastline position. Coastlines continuously change due to wave, tide, and etc. actions. Therefore, it is necessary to have enough information on coastline position not only in the present time, but also in the past and future in order to organize scientific and engineering activities in a coastal zone. Satellite data are the best and most economic method for collecting such data. In this paper, three images provided by TM sensor of Landsat satellite were used for extracting coastline positions and investigating their changes in a period of 13 years. The images were prepared for further processing like radiometric corrections and geocoding. Then shoreline position corresponding to each image was extracted and compared with others. Moreover, different prediction methods were employed to estimate shoreline position in 2005 and 2010. Data are not timely equidistant, therefore, the results of the least square method are not accurate enough. However, the results of other methods are acceptable.
