2012 National Anthropogenic Barrier Dataset (NABD)
Entry ID: NFHP_NAPD-2012

Abstract: ABSTRACT: The main objective of this project was to develop a dataset of large, anthropogenic barriers that are spatially linked to the National Hydrography Dataset Plus Version 1 (NHDPlusV1) for the conterminous U.S. and the high resolution National Hydrography Dataset (NHD) for Alaska (1:63,000 scale) and Hawaii (1:24,000 scale) to facilitate GIS analyses based on the NHDPlusV1/NHD and NID ...

Purpose: PURPOSE: Dams spatially linked to the NHDPlus/NHD offer an advantage to datasets of dams not linked to the NHDPlusV1/NHD because dams represented by points are located on flowlines representing stream and reservoir waterbodies. These qualities will allow managers and researchers to perform analyses and make more informed decisions when stream connectivity is considered in management plans and/or ... View entire text

Quality ATTRIBUTE ACCURACY REPORT: No formal attribute accuracy tests were conducted.


COMPLETENESS REPORT: Data set considered complete at time of metadata creation. Please read the metadata document for details.

HORIZONTAL POSITIONAL ACCURACY REPORT: While linking points to the NHDPlusV1 we verified locational information of the points using visual cues and by using locational information provided within the National Inventory of Dams (e.g. City, Stream Name, Legal Description and others).
