Below is a false color image of the southern end of Daufuskie Island, where the colors on the image represent the data values — in this case, elevation. The term "false color" simply means that the image is not a photograph, and that you should use the color bar to interpret what the colors mean. Note the lighter blue spot in the center of the inlet near Mungen Creek. This feature is a small sandbar. You can make a similar image using the BeachMapper software application provided on the second volume of this CD-ROM set. For more information about the BeachMapper Application, click here.

Portable Document Format (PDF) maps have been created to show LIDAR data for South Carolina's beaches and islands. PDF maps will allow you to zoom in on the data and print the maps at better resolution. However, because of the intense density of the data, the PDF files will not draw properly from your browser. If you have Adobe Acrobat Reader® software installed on your computer, you can view the maps by navigating to the pdf/islands directory on this CD-ROM and double click on a file. A directory of maps is available in the readme.txt file. Adobe Acrobat Reader software has been provided on this CD-ROM.

The southernmost of the South Carolina sea islands, Daufuskie Island is bounded by the Calibogue Sound to the northeast and Mungen Creek to the southwest. Relatively wide (more than 2.5 miles), the entire island has been classified by OCRM as an unstabilized inlet zone. Erosion rates have been monitored since 1988; island wide long-term erosion rates average -4 to -5 feet per year, with the highest rates of -10 to -11 feet per year found near the south end.
The island is accessible only by boat and development has been slow. In the mid-1970s only about 200 people lived on the island. Longtime residents were the descendents of slaves, but gradually these landowners have sold their property to developers.
Beach profile surveys are conducted in the spring and fall at approximately 400 monitoring stations throughout the State of South Carolina. Various agencies participate in the beach profile collection, including The South Carolina Department of Health and Environmental Control (SCDHEC) Office of Ocean and Coastal Resource Management (OCRM), Coastal Carolina University, and the College of Charleston. The results of the surveys provide a snapshot of the beach face. Over time, these surveys can be compiled to determine if and how the profile of the beach is changing. Below is a map of the stations and a sample of the profiles that can be extracted from the data. The beach profile data compiled by OCRM is provided on the second volume of this CD-ROM set.
