| General GIS Data | Elevation | Fly-through movie of the Duplin River based on a synthesis of multibeam SONAR and LIDAR data (public file request) Description - Fly-through movie of the Duplin River and the associated intertidal area. Bathymetric data were collected using multibeam SONAR by personnel from the Burroughs & Chapin Center for Marine and Wetland Studies (BCCMWS) in December 1999. Intertidal topographic data were collected using airborne LIDAR contracted for by GCE-LTER. |

| Duplin DEM Description - A high-resolution digital elevation model (DEM) of the Duplin river, with a 1m2 resolution, constructed through the classification and analysis of a series of aerial photograph sets taken during a flood tide in April 2004. Available for download is a zip archive containing an ESRI GRID and ERDAS .img files. A .pdf file of two combined reports describing the methodology used to generate the DEM is also provided. We recommend extracting the entire zip archive to a separate empty folder. Points with Z values < -0.1 m should be discarded because they are interpolations below the lowest water height recorded. |

| Other | NOAA LiDAR Description - This LiDAR-derived data was collected by the Joint Airborne Lidar Bathymetry Technical Center of Expertise using the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system. The data includes hydrographic and topographic data and were collected to depict the elevations above and below water along the immediate coastal zone at 3 m resolution. The survey generally extends 750 meters inland and up to 1500 meters over the water (depending on water depth and clarity) and this subset extends from the Sapelo Sound south to Saint Simons Island. The goal of the project is to collect data covering the shoreline of the conterminous United States where feasible. The project is lead by the U.S. Army Corps of Engineers. This zip archive contains an ESRI GRID file and associated metadata. We recommend saving the contents to a new, empty folder. A jpeg image of the data set is also available for download/viewing. |

| GCE 2001 NLCD Description - 2001 30 m resolution National Land Cover Database (NLCD) subset of the GCE study domain developed by the US Geological Survey. The zip archive contains ESRI GRID files and associated metadata. A jpeg image of this dataset is also available for download separately. We recommend unzipping the archive into a new, empty folder (e.g. GCE_01_NLCD). |

| GCE 1992 land cover Description - 1992 60 m resolution land cover dataset of the GCE study domain developed by ERDAS, Inc. for the Georgia DNR. The zip archive contains ESRI GRID files and associated metadata. A jpeg image of this dataset is also available for download separately. We recommend unzipping the archive into a new, empty folder (e.g. GCE_92_landcover). |

| GCE 10m NED Description - 10 m resolution National Elevation Dataset (NED) of the GCE study domain developed by the US Geological Survey in 1999. The zip archive contains ESRI GRID files and associated metadata. A jpeg image of this dataset is also available for download separately. We recommend unzipping the archive into a new, empty folder (e.g. GCE_10m_NED). |

| Imagery | Aerial Photography | Sapelo Island 2006 Description - Color, ortho-rectified 0.5 m pixel resolution image of Sapelo Island taken in 2006 and obtained through the USGS Seamless Data Distribution System. Several images were collected and mosaicked together by the GCE-LTER using ArcMap v.9.2. The spatially referenced GeoTIFF image (3.24 GB) is available only upon request. |
