| description | Tuz Lake and its surrounding lakes (Tersakan Lake, Duden Lake, Bolluk Lake, Esmekaya Lake, Kopek Lake, Akgol) are placed in
the Central Anatolia region. These lakes maintain the ecosystem's integrity and make a good habitat for numerous bird species,
especially flamingos. The Duden Lake is located within the boundaries of the Tuz Lake Special Environmental Protection Area and
was declared as a protected area in 1992. The surface and underground water around Kulu District of Konya feed the Duden Lake,
which is tectonically formed through the Kulu Stream. The lake with the average area of 860 hectares is unfortunately at the risk of
extinction. Remote sensing has been the most useful tool to obtain spatial and temporal information about wetlands and it provides
up-to-date, accurate, and cost-effective information. Remote sensing methods and applications are used quite effectively on wetlands.
The traditional pixel-based classification method is applied to different satellite images in wetlands over many decades, and the usage
of object-based classification method has started recently comparing to the pixel-based one. This study aimed to determine the
coastline of the wetlands. Sentinel 2 satellite images, which provide free access and high spatial resolution, are used to observe the
coastline of Duden Lake through the usage of pixel-based and object-based classification methods in all the seasons. The
applicability of the methods in the determination of shallow wetland coastline is studied and evaluated. The results of the pixel-based
and the object-based classification images are compared by accuracy assessment. |
