Digital Orthophoto Quarter Quarter Quadrangle (DOQQQ)

Small image of Geologic Map Data The digital orthophotography was produced as part of the South Carolina Oyster Beds Imaging effort to support the mapping of intertidal oyster reefs. The project area was over specified areas of the South Carolina coastal critical zone where oysters have been traditionally mapped by the South Carolina Department of Natural Resources, Marine Division.

The digital orthophotos in this series have a theoretical ground resolution of 0.25 meter. The extent of the DOQQQs for the project area range from the Hilton Head area in the southern part of South Carolina to the Myrtle Beach area in the northern part of the state. The Imagery flight dates are 2003-2006 taken in the spring - fall.  OCRM, SCDHEC extended the project area up to the saltwater/freshwater line and imagery flight dates are 2006-2007 taken in the spring - fall. A compressed version of the images are available in both Natural Color and Color-infrared.

A DOQQQ can be incorporated into any geographic information system (GIS) that can manipulate raster images. It can function as a cartographic base for displaying, generating, and modifying associated digital data.
