Description: The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are used to portray surface water on The National Map. The NHD represents the drainage network with features such as rivers, streams, canals, lakes, ponds, coastline, dams, and streamgages. The WBD represents drainage basins as enclosed areas in eight different size categories. Both datasets represent the real world at a nominal scale of 1:24,000-scale, which means that one inch of The National Map data equals 2,000 feet on the ground. To maintain mapping clarity not all water features are represented and those that are use a moderate level of detail. Great Smoky Mountains National Park makes these data available in this form such that users can: effectively manipulate data for park mapping activites that do not require the aquistion of a large, nation-wide data set; alter symobology and rendering parameters natively; restrict analysis of geospatial data to an extent that coincides with the park footprint.
