This data set contains regions representing areal NHD hydrographic waterbody features. Basic waterbodies such as lake/pond features are represented here. They portray the spatial geometry and the attributes of the feature. These water polygons may contain NHDFlowline artificial paths to allow the representation of water flow. Other NHDWaterbody features are swamp/marsh, reservoir, playa, estuary, and ice mass. The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. The data was originally published by the USGS then it is modified by the NHD data steward for Florida (FDEP). When received from FDEP, this data was originally in geodatabase format. When in shapefile format the data loses the network functionality of the geodatabase. Please contact the FDEP if you need the original geodatabase. |
