Below is a false color image of Hunting 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 on the image to interpret what the colors mean. This image shows the northern portion of the island where it is separated from Harbor Island by Johnson Creek. Sandbars have formed here where the creek empties into the ocean. 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.

Hunting Island, located in Beaufort County, is owned by the State of South Carolina and managed by SC Parks Recreation and Tourism (SCPRT) as a state park. Harbor and Fripp Island, both extensively developed, bound Hunting Island to the north and south respectively. In addition to a few privately owned cottages, development is limited to scattered park buildings, camping facilities, recreational/educational trails, and park-owned overnight cottages.
The island has historically been highly erosional, with long term rates ranging from -7 to -15 feet per year. A lighthouse constructed in the 1800s, designed to be dismantled and moved as the island eroded, was relocated a mile inland from its original site by the early 1900s. A valuable public resource, Hunting Island is one of the few undeveloped islands to undergo beach nourishment. The first renourishment efforts began in the late 1960s. From 1968 through 1980, approximately 3.5 million cubic yards (cy) of sand at a cost of $4.2 million was placed on the beach. The most recent project completed in 1991 placed over 715,000 cy of sand on 7,500 feet of beach. Project cost was close to $3 million dollars and was funded by SCPRT and the SC Coastal Council Beach Management Trust Fund.
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.
