Kentucky Public Service Commission (PSC), 2006, Electric Service Areas.
This is a Vector data set. It contains the following vector data types (SDTS terminology):
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 6378137.000000.
The flattening of the ellipsoid
used is 1/298.257222.

Coordinates defining the features.
| Value | Definition |
|---|---|
| Edge Not Matched | Where regulated electric service area boundaries did not line up well at the edges of adjacent PSC certified territory maps and the gap between line ends represented 300 feet or less, a straight "edge not matched" line was inserted to connect the two discontinuous pieces. This "connector" might run in any direction. |
| Edge Not Matched Mun | |
| Missing Data | When a boundary segment for a regulated electric service area was missing from the PSC certified territory maps and there was no alternate source of information, a line was inserted to close the polygon. If a portion of a service area that straddled more than one quadrangle was omitted from one of the quads, the missing side was drawn as a straight line along the quad edge. Some missing data lines extended a service area boundary line from the shore of the Ohio River to the State of Kentucky Boundary mid-stream or on the opposite shore. Some missing data segments formed a missing boundary running along the Warren/Allen County line (tracing the Barren River and Bays Fork.) |
| Missing Municipal | A line inserted to close a municipal utility service area where boundary line data was missing. If the boundaries of a municipal utility were entirely unknown, a circle was drawn around the boundary of the city as it appeared on the USGS topographic map. Missing (Municipal lines are greater than 300 ground feet in length except where close intersections or a change in map source breaks them into smaller segments.) |
| Municipal Line | A boundary of a municipal utility service area. The PSC does not regulate Municipal electric utility service area boundaries. |
| PSC Line | An electric service area boundary that the Kentucky Public Service Commission (PSC) regulates. The source is either a certified territory map on file at the PSC or a map filed with a case before the PSC. |
| State Boundary | State of Kentucky boundary. These were digitized off USGS quadrangles and checked against DRGs. |
| Unofficial Boundary | A regulated boundary, other than a municipal boundary, coming from a reliable source outside of the PSC certified territory maps. The map source is not legally certified by the PSC. |

The coverage fulfills the requirement of Kentucky Revised Statute section 278.017 that the Kentucky Public Service Commission (PSC) prepare a map or maps of uniform scale to show the certified service territories of all retail electric suppliers in Kentucky.
Attribute accuracy tests were only applied to the arc feature class. All arcs were verified as having some type of line classification. Aspects of line position and length were tested to help ensure correct classification. An example was verifying that arcs forming boundaries of municpal polygons had some type of municipal line classification. All distances examined were in Kentucky One Zone.
The coverage was digitized from paper maps at the scale of 1:24,000 or larger (greater detail.) Usually, the base map was a USGS quadrangle. The standard of horizontal accuracy for 1:24,000 USGS topographic maps is 40 feet, equivalent to 12.1920 meters. Therefore, the horizontal position of service area boundaries in this coverage cannot be regarded as any more accurate than 40 feet of true ground location.
Adjacent arc nodes in precedent coverages were not snapped together. Straight lines were inserted to close unsnapped polygons. If the line segment represented 300 feet or less in a Kentucky One-Zone projection, it was regarded as equivalent to a "snap" and was assigned the same line classification as one or both of its neighbors. A dissolve command was then applied allowing these to merge with neighbor arcs. Arcs were also inserted to close polygons where data was missing. These arcs were classified as "missing data" or "missing municipal" lines.
