    Description: 
      Abstract: 
      The hydro polygon/arc coverages were created using TIGER/LINE 2000 
      shapefile data gathered from ESRI's Geography Network. The individual 
      county hydrography line 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 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 paint a complete picture. 
      Purpose: 
      The BTS desires 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). 
      Supplemental_Information: 
      The 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. To

        1) Downloaded zipped shapefiles from www.geographynetwork.com; 2) 
        Converted the Shapefiles to Coverages; 3) Removed all intermittent water 
        features H02, H12, H22, H32, H42, H60, H71, H72, H80, and H81 from the 
        database coverages; 4) Flagged arcs to be retained in the output 
        coverage based on relative importance and research using the Internet 
        and state maps; 5.) Added attributes to polygons to denote name 
        description and land/water. These attributes were then populated by user 
        input using mapping resources such as state and county maps; 6) Added 
        attributes to both arcs and polygons to denote navigable waterways. For 
        single line features, the arcs were flagged. If a feature contained 
        polygons, the polygons only were flagged; 7) States were then appended, 
        extra items dropped, data released.

        Process_Description: 
        When UTN processed the TIGER dataset for State, County and Hydrographic 
        (line and polygons) it created a 3-mile buffer around Texas shorelines. 
        This buffer removed the island off the coast of Texas. To correct this 
        error, BTS used ARC/INFO to remove the 3-mile buffer to capture the 
        islands along Texas. To capture the islands the state dataset needed to 
        be reselected, by selecting the code = 1. This process created a few 
        inaccurate polygons and they were removed. To create the final datasets, 
        the datasets were dissolved and regions created on STFIPS and County 
        FIPS.
