Edge Detection in Microgravity Data: An Example of Bornova Plain and Its Surroundings, Western Anatolia, Turkey
Öz
Tilt
angle (TA), total horizontal derivative (THDR) and tilt angle of the horizontal
gradient (TAHG) methods were used to determine the structural edges in the
Bornova Plain. First of all, a model representing the study area was formed in
this study consisting of two steps, synthetic and field study, by using prisms
in different depths and sizes.
Structural edges were tried to be determined by applying these three
methods to the gravity anomaly of this model. The mentioned edge detection
methods were applied to the residual gravity anomaly, which was calculated by using microgravity data
collected in the Bornova Plain, (Izmir, Turkey) in the next step. Although all
of the three methods produce good results both in synthetic and field studies
in general, the TAHG method produces more usable results since it makes the
structural edges more dominant.
