![]() ![]() While positive factors in the physical environment stimulate tourism activities, negative factors are a threat to tourism. In this respect, there is an important relationship between tourism and physical environment (Lo et al. The environmental impact is an important factor in increasing the likelihood of tourists to choose, as well as creating a sustainable tourism need for a specific region or country (Dunets and Zhogova 2018). Tourism, which is one of the industries showing a fast and steady development, emerges as an industry that needs natural, environmental, and cultural resources and uses these resources as economic input (Duran 2011 Ko and Stewart 2002 Ahmad et. Although the spatial resolution of Landsat data, it has been observed that the power to analyze annual variation differences is lower than Sentinel-2. However, the most optimal way to detect long-term changes in the shoreline is to use Landsat data. Spatial resolution in satellite images is vital for shoreline detection. As a result of the study, when the Pearson’s r value between EPR and LRR was examined, r was found 0.916 and 0.944 for 5-year and 35-year data, respectively. Five-year and 35-year changes were compared with Linear Regression Rate (LRR) and End Point Rate (EPR) analyses. The obtained shorelines were analyzed with the Digital Shoreline Analysis System (DSAS) tool and the changes in the coastal areas were determined statistically. In the study, water areas on the coastline were determined by object-based classification and multiresolution segmentation method with the Modified Normalized Difference Water Index (MNDWI). The focus of the study is to analyze long-term coastal change with Landsat data and the data obtained every 5 years between 19 and to analyze short-term change with annual Sentinel-2 data between 20. In this study, which is an important tourist city of Antalya, Turkey, and the world, coastal changes using historical and recent satellite data have been analyzed. Monitoring short-term and long-term changes in coastal areas is important to prevent damages that may occur due to natural and human factors and protect the shorelines. Since coastal areas are both economically and socially important, monitoring shoreline changes has become one of the important research areas. Uncontrolled tourism activities cause the destruction of nature and deterioration of the ecological balance. ![]()
