Description:

Abstract:

This GIS data set represents National Hydrography Dataset (NHD) Subbasins. Subbasins are subdivisions of the basins. Subbasins are the fourth level (8 digit) of the hydrologic unit hierarchy, formerly called "cataloging units".
This file contains Hydrologic Unit boundaries and codes for the Florida. The NHD data set is a seamless National representation of Hydrologic Unit Code (HUC) boundaries at HUC2 to HUC12 levels compiled from U.S. Geological Survey (USGS) National Hydrography Dataset (NHD) and U.S. Department of Agricultural (USDA) National Resources Conservation Services (NRCS) Watershed Boundary Dataset (WBD) sources.

Purpose:

This data is intended primarily for geographic display and analysis of regional and national data, and can also be used for illustration purposes at intermediate or small scales (1:250,000 to 1:2,000,000).

Access_Constraints:

None. Acknowledgment of the originating agencies would be appreciated in products derived from these data.

Use_Constraints:

These data were digitized and edited from best available sources at a scales ranging from 1:24,000, or better, up to 1:2,000,000. This data is not intended to be the authoritative source for hyrologic units, but only as a reference to NHD data that has some interdependecies with hydrologic unit delineation for reach code assignments.
