- Description:

- Abstract:
-
The County Boundary with Detailed Shorelines database was created using TIGER/LINE 2000 shapefile data gathered from ESRI's Geography Network. The individual county shapefiles were processed into Arc/Info coverages and then appended together to create complete state/county coverages. BTS Hydrographic data was integrated to create detailed shorelines.
- Purpose:
-
The United States County Boundary database is a geographic database of county political boundaries. The database includes boundaries for all 50 states plus Puerto Rico and Washington D.C..
- Supplemental_Information:
-
The BTS County Boundary Database contains TIGER 2000 geometry and attributes. To find out more about TIGER/Line files and other Census TIGER data base derived data sets visit <http://www.census.gov/geo/www/tiger>.

- Process_Description:
-
When UTN process 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.
