Resource Abstract:
- description: The Electric Substation geospatial data layer contains point features representing transmission substations and
some distribution substations in California. These substations are fed by electric transmission lines and are used to step-up
and step-down the voltage of electricity being carried by the lines, or simply to connect together various lines and maintain
reliability of supply. These substations can be located on the surface within fenced enclosures, within special purpose buildings,
on rooftops (in urban environments), or underground. A substation feature is also used to represent a location where one transmission
line "taps" into another. The transmission line, substation and power plant mapping database were started in 1990
by the CEC GIS staff. The final project was completed in October 2010. The enterprise GIS system on CEC's critical infrastructure
database was lead by GIS Unit in November 2014 and was implemented in May 2016. The data was derived from utility companies
and USGS topographic map, Some of the data was rectified from GE and Platts substation geospatial data. The sources for the
substation point digitizing are including sub-meter resolution of Digital Globe, Bing, Google, ESRI and NAIP aerial imageries,
with scale at least 1:10,000. Occasionally, USGS Topographic map, Google Street View and Bing Bird's Eye are used to
verify the precise location of a facility.; abstract: The Electric Substation geospatial data layer contains point features
