Florida Hydrography Dataset (FHD) (Formerly NHD) - Areas (24k)

The Florida Hydrography Dataset (FHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the state's surface water drainage system. The FHD is based on the original National Hydrography Dataset (NHD) data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution FHD, generally developed at 1:5,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) The FHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The FHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.
