Abstract
This polyline shapefile depicts hydro coverages that were created using TIGER/Line 2000 shapefile data gathered from ESRI's Geography Network. The individual county hydrography polyline shapefiles were processed into Arc/Info coverages and then appended together to create complete state coverages. They were then edited to remove unwanted features, leaving a state-by-state database of both important and navigable water features. Attributes were added to denote navigable features and names. Also, an attribute was added to the polygons to denote which were water and which were land features. The state databases were then appended together to create a single, nationwide hydrography network containing named arcs and polygons. These features also contain a state Federal Information Processing Standards (FIPS). Because some of the hydro features are represented by lines instead of polygons, the complete hydro dataset consists of 2 shapefiles, one for lines and one for polygons. They must be used together to present a complete picture. This layer is part of the 2014 National Transportation Atlas Database.
Purpose
The National Transportation Atlas Databases 2014 (NTAD2014) is a set of nationwide geographic datasets of transportation facilities, transportation networks, associated infrastructure and other political and administrative entities. These datasets include spatial information for transportation modal networks and intermodal terminals, as well as the re¬lated attribute information for these features. This data supports research, analysis, and decision-making across all transportation modes. It is most useful at the national level, but has major applications at regional, state and local scales throughout the transportation community. The data used to compile NTAD2014 was provided by our partners within the United States Department of Transportation (USDOT) and by other agencies throughout the United States Federal Government. These contributors are the actual data stewards and are ultimately responsible for the maintenance and accuracy of their data. This data was developed because the Bureau of Transportation Statistics (BTS) wants a single nationwide database that has polygons/attributes for major rivers and lakes, is consistent across state lines and has the most accurate data available. This database will be used primarily for map production, basic queries and will be distributed as part of the National Transportation Atlas Databases (NTAD) 2014.

Bibliographic information

Supplemental information The OST-R/BTS HYDRO Database contains TIGER 2000 geometry and attributes. UTCTR flagged this database to represent major water features and edited the geometry to insure polygons would fill for cartographic representation.
