Determination of changes in coastal regions and monitoring these changes are crucial for the management of coastal areas and sustainable development. Various methods are utilized in monitoring the changes in coastal areas and remote sensing technology is one of the most important methods. In this study, a map generated by the French in about 1890s with the scale of 1/10000 was vectorized to evaluate the first condition of coastal region of Zonguldak city. By vectorization of this map, some urban constructions, harbor details and determination of coastal region was detected. Furthermore, it is aimed to reveal the changes in coastal stretch using object-based image analyzes (OBIA), and for this purpose one high resolution satellite image acquired on 2015 from Worldview-2 satellite was utilized. This image was processed using eCognition software, and coastal stretch and water body were determined by OBIA. Vectorized map generated in 1890s and manually vectorized results were compared. As a result of the analyses, it is revealed that object-based classification techniques can be applied to extract the coastal stretch semi-automatically and the classification results are similar to vectorization results. As a consequence, monitoring the temporal changes in coastal regions via OBIA using high resolution satellite image is an effective method and the obtained results can be integrated to GIS easily.
