GRANIT Metadata for New Hampshire Hydrography Dataset - CU 01080103 - CT-Johns River to Waits River

Title: New Hampshire Hydrography Dataset - CU 01080103 - CT-Johns River to Waits River
Time Period of Content: 1956 - 2006 Initial Publication Date: 01/2006
Originator: Complex Systems Research Center, University of New Hampshire
Abstract:
The New Hampshire Hydrography Dataset (NHHD) 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 NHHD, developed at 1:24,000 scale, is an extract from the high-resolution National Hydrography Dataset (NHD) housed at the US Geological Survey. The NHHD contains reach codes for networked features, flow direction, names, stream orders and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the the Atlantic Ocean. The NHHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee.
