The flattening of the ellipsoid used is 1/298.257222.
Arbitrary powerhouse ID in SCADA database.
The DCCED does not intend that the communities listed in the Commerce Alaska Community Database should be construed as a definitive listing of Alaska communities. There is no official definition of the term "community" in Alaska, and this department does not generally make formal determinations regarding whether or not a specific group of persons comprises a community. Communities currently listed in the database include all legally incorporated municipalities (cities and boroughs), all federally-recognized Native villages and all "Census-Designated Places" (recognized by the 2000 U.S. Census). The list also includes a number of other "communities" that do not come under these preceding classifications. There are numerous "place name" locations, named municipal neighborhoods and historical locales that are not included in the current community list. NA: Not applicable.

The data provides engineers, consultants, planners, and resource managers with information on the location of rural community powerhouses in Alaska and identifies locations for further installation by other agencies. In rural communities throughout Alaska, electricity is generated by a small local "system" (generation and distribution) using diesel fuel at a cost that is three to five times higher than that in urban parts of the state. Of 200 rural communities, approximately half are served by cooperatives or another form of utility that performs under a well-established organization. Others are served by very small entities, many which experience technical and administrative problems due to lack of economies of scale and/or lack of specialized skills in the community.

Data sources used in this process:
Project locations were drawn from the nearest community, according to locations provided by the 2000 Census.
Unknown. Community locations were drawn from the 2000 Census. However, the locations of statewide towns and villages listed in the Census were likely entered by latitude-longitude, digitized from USGS 1:250,000 quadrangle maps, and heads-up digitizing from USGS 1:250,000 maps based on relative positioning of digital hydrography and digital township lines. Many locations were later updated by snapping them to points in the USGSNAMES coverage obtained from USGS. See the "Lineage" section below for additional information.
This dataset includes geospatial information about the locations of the projects maintained by the Rural Power Systems Upgrade Program, Alaska Energy Authority.
Polygon topology present and clean on appropriate data. Other data are line, point, or annotation data and do not require topologic relationships.
