The map area is within the Highlands 7.5-minute quadrangle and includes the town of Highlands, about 3 miles north of the Georgia State line. This map was produced as part of a cooperative hydrogeologic project, the Piedmont-Mountains Ground Water Project, between the U.S. Geological Survey and the North Carolina Department of Environment and Natural Resources. The goal of the project is to better understand the hydrologic characteristics of major hydrogeologic settings in the North Carolina Piedmont and Blue Ridge geologic provinces, for the purpose of ground-water resource planning. The main focus of the project is an intensive study of small watersheds that are considered to be representative of larger areas within each geologic province. Map-Construction Summary: Geologic data were compiled digitally in the field using a PDA with GPS capabilities. Field stations, outcrops, and contacts were recorded using ArcPad and saved in ArcView shapefile format. Attribute data for each station were recorded in an MS Access file using Pendragon Forms. Editing was done in ArcGIS 8.3 using the Geodatabase format and converted to shapefiles. The base-map information consists of hydrology, roads and culture, and hypsography. The base-map data were scanned at 400 dpi from film positives of the Highlands, N.C.-Ga., 7.5-minute quadrangle (1946, photorevised 1980). The TIFF images were rectified using ArcGIS 8.3, then converted to bitmap in Adobe Photoshop and saved to .psd (Photoshop document) for easy import into Adobe Illustrator.
