Land Use/Land Cover and Change Detection of Isparta Eğirdir Lake Basin Using Sentinel 2 Satellite Images

Abstract

Land use and land cover (LULC) change is a global environmental issue significantly impacting sustainable development and environmental quality. The process of analyzing LULC change involves remote sensing and GIS using machine learning techniques. This study aims to analyze the LULC change in the Isparta Eğirdir Lake basin, a crucial ecosystem and economic resource in Turkey, considering its biodiversity, agricultural potential, touristic value, and water resources. Sentinel 2A satellite images with a spatial resolution of 10m from 2015 to 2023 were used for the analysis. NDVI, NDWI, and NDBI analyses, along with a supervised classification method, were employed to identify the direction and magnitude of the change. As a result, the surface area of Lake Eğirdir, Turkey's second-largest freshwater lake, is gradually decreasing, with a noticeable withdrawal of 50-60 meters, particularly in the Hoyran section of the lake.
