In the study area, after having evaluated images dated 1935,
1972 and 2006 using digital photogrammetric methods, coastline
layers were digitized separately on 3D model and their maps were
obtained. The changes in coastline, as a result of the filled area,
coastal erosion, sand taken from the sea, etc., were also examined
from those maps. In addition to these, the overlapping layers which
belong to different date periods (1935 - 1972 and 1972 – 2006) and
the area between the intersected layers have been calculated. If the
area is found towards the sea (caused from the filled area) or
towards the land, it happened because of the coastal erosion or as
a result of taking something from the seaside. In the following, the
figure is a sample of the calculation of the areas which were gained
by filling, erosion, sand taking, etc. The drawings, which were
transferred to Microstation and saved as dxf, were transferred to the
ArcGIS 9.2 software by ESRI for topology building. After that, the
area of the coastline changes was calculated separately in the time
periods of 1935 to 1972 and 1972 to 2006.
