Figure 2.9. A) Schematic showing the flight path of an aerial photographic survey that follows the coastline in North Myrtle Beach.  Surveys are conducted at low tide with adjacent, overlapping photographs to allow for continuous coverage. B) Example of aerial photograph showing coastal development and shoreline morphology at Cherry Grove.  C) Enlarged area of the photograph showing prominent features such as the sand fence, wet-dry line and low-tide line.  The wet-dry line is typically used to delineate shoreline position on aerial photographs.  Shorelines delineated from successive surveys are compared to assess change in position over time.
