Determination of coastline is extremely essential especially in coastal cities where there are harbors and ship transportation. In addition, the monitoring of coastline would be helpful to gain valuable information about sea level variations during the years. As conventional methods including RTK GPS are manpower, cost and time consuming, the aim of this study is to utilize the pairs of polarimetric SAR images for water and land distinction in Anzali region. This approach is an effective, precise and fast way which requires less money and manpower. In this study polarimetric SAR images of ALOS sensor have been used which belongs to Japan. SAR images are in HH and HV mode.
