Description This data set is a digital map of the 8-, 10-, and 12-digit hydrologic unit boundaries for Georgia and parts of Alabama, South Carolina, North Carolina, FLorida, and Tennessee. The boundaries were delineated on 1:24,000 7.5 minute USGS topographic quadrangles which were scanned into a digital image and vectorized interactively on a computer graphic display. The hydrologic unit polygons are tagged with the appropriate 8, 10, and 12 digit codes. (Release 2.0, June 2001)
