Abstract: | |
Hydrologic units being mapped and digitized by the Soil Conservation Service (SCS) define the locations of river basins, watersheds and sub-watersheds. Areas being digitized include the existing 8-digit USGS hydrologic units and SCS 11-digit (approximately 250,000 acres in size) and 14-digit (approximately 10,000 to 40,000 acres in size). Digitizing is done by line segment (vector) format in accordance with SCS digitizing standards and specifications. Standards are also established for mapping the hydrologic units (HUCs). HUCs are being mapped and digitized on either the 1:24,000 or 1:100,000 USGS quadrangle maps. |
