Title: LATAs for Local Exchange Carriers

Abstract:

LATAs are Local Access Transport Areas, which are defined by grouping exchange areas. Local telephone companies are permitted to offer local or long distance telecommunications services within these regions. It initially provided a basis for determining how the assets of the former Bell System were to be divided at divestiture. A LATA may cross state boundaries.

1. How should this data set be cited?

   Kentucky Public Service Commission (PSC), 2002, LATAs for Local Exchange Carriers.

2. What geographic area does the data set cover?

   West_Bounding_Coordinate: -89.571121

   East_Bounding_Coordinate: -81.965126

   North_Bounding_Coordinate: 39.147629

   South_Bounding_Coordinate: 36.496998

3. What does it look like?

4. Does the data set describe conditions during a particular time period?

   Calendar_Date: 2002

   Currentness_Reference: publication date

5. What is the general form of this data set?

   Geospatial_Data_Presentation_Form: vector digital data

6. How does the data set represent geographic features?
   1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • G-polygon (7)

   2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378206.400000.
      The flattening of the ellipsoid used is 1/294.978698.
      

7. How does the data set describe geographic features?

   LATA

   FID

   Internal feature number. (Source: ESRI)

   Sequential unique whole numbers that are automatically generated.

   Shape

   Feature geometry. (Source: ESRI)

   Coordinates defining the features.

   LATA

   Local Access Transport Area Name

   COUNT

   Number of exchange areas used to define the LATA in Kentucky

   SQR_MI

   Square miles calculated by summing square miles of exchange areas, which were calculated with Kentucky Single Zone State Plane Coordinates.
