Below is a false color image of Harbor 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 depicts the upper part of Harbor Island. This image demonstrates well the "swath-like" nature of the data. 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.

Harbor Island, in Beaufort County, is located between Hunting Island and Johnson Creek to the southwest and the open water of St. Helena Sound to the northeast. Beachfront development is primarily single-family residential mixed with a few condominium buildings. The entire island is classified as an unstabilized inlet zone. While the shoreline is very dynamic, the trend is generally accretional. Harbor Island is a transgressive island formed as sand is transported and deposited up St. Helena Sound. Harbor Island was impacted by the hurricane of August 1893, known as the "Sea Islands Hurricane," that destroyed Edingsville Beach. Winds of 120 miles per hour accompanied by a storm surge of 20 feet flooded the island. Thousands of lives were lost and the economy was ruined in this region.
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.
