Title: County Boundaries clipped to shoreline from Teleatlas, NA for Regions 1, 2 and 3 in EPA Region 2 Oracle/Spatial/SDE Database [TANA.COUNTY]
Abstract: The Dynamap(R)/2000 County Boundary file is a non-generalized polygon layer that represents all U.S. government-defined entities named County. A County is a type of governmental unit that is the primary legal subdivision of every U.S. state. In Louisiana, the County-equivalent entity is 'parish.' In Alaska, the statistically equivalent entities are the organized 'boroughs,' 'city and boroughs,' 'municipalities' and 'census areas.'
Purpose: The purpose of this layer is to provide to users who need them accurate cartographic representations of County boundaries to overlay with other Tele Atlas(R) layers or products.

Publication Date: 200704
Progress: Completed
Frequency: In general, census boundaries are updated every 10 years after the release of U.S. Census Bureau TIGER/Line(R) files containing the new boundaries resulting from the latest decennial census. County additions and deletions that are received from the U.S. Census Bureau (TIGER/Line(R) files) prior to July of each year are included in the next January product release. Example: A County change received from the Census Bureau in June 1999 would appear in this product's January 2000 release. County changes received from the U.S. Census Bureau (TIGER/Line(R) files) after July of each year are incorporated into the following year's January product release. Example: A County change received from the Census Bureau in August 1999 would appear in this product's January 2001 release. County boundary annexations or adjustments are not captured. County boundaries are current to 2002 TIGER/Line(R) files. On-going realignment work on the Tele Atlas(R) database may result in improved horizontal accuracy of County boundaries in some areas.
