RADAR systems and data sets in Remote
Sensing (RS) and Geographic Information Systems (GIS) technologies have been
used quite frequently in recent years, with their ability to obtain reliable
and continuous images for different analyzes and change detection. It is
preferred especially because it can reveal sensitive measurements in studies
such as land change, landslide, erosion, earthquake, crop productivity, snow
depth detection in winter recreation areas. While detecting all these changes,
different band properties and resolution values of RADAR images are used.
Within the scope of the study, snow-water
depth in the areas affected by the 7.8 magnitude earthquake that took place on
06.02.2023 on the line of Nurdağı district of Gaziantep and Bahçe district of
Osmaniye between 29.01.2023 and 10.02.2023, between the altitudes of 1000-1793
meters. change in remote sensing was investigated by using interferometry
method with the support of RADAR images. While applying this method, SAR based,
C band supported, Sentinel 1A RADAR image sets were used. Under normal
conditions, the changes in that region were compared with the changes in the
previous year and the effect of the earthquake was examined. It has been
determined that there is a 20 cm change between the relevant dates as one moves
from the higher areas to the lower areas. Differences were found when compared
with previous years. Consistency values between 0.5 and 1 and acceptable result
values set an example for studies to be carried out in larger areas. It has
been revealed that natural disasters are an important factor in land use
planning and other investment and planning studies to be made and that they
should play an active role in planning.
