GIS Data Development: Integration of vector and attribute data from multiple (10+) external sources and with multiple geographic map layers (including transmission lines, substations, power plants, towers and poles, utility service districts, political boundaries, roads, fire hazard zones and bodies of water).Enables more robust control and management of ISO GIS data.Can be used to support to support a wide array of ISO projects that require map production and database integration and.Unified GIS Model: Development of a unified GIS data model that:.Solutionįarallon developed a Unified GIS data model that successfully merged the State’s major power generators’ GIS data into a single, consistent, validated, and audited database. The ISO asked Farallon to help develop the State’s first complete and positionally accurate electrical transmission grid by integrating raw data dumps from the State’s primary electricity generators and transmitters, including Pacific Gas and Electric Company, Southern California Edison, San Diego Gas and Electric, and the California Energy Commission. To support the management of the electrical grid in response to factors such as wild land fires and extreme weather, the ISO recognized that access to a geographically accurate representation of the grid through a GIS would be critical. ISO’s control area is the second largest in the U.S. The California Independent System Operator (ISO) is tasked with managing the transmission of electricity through the State’s network of high voltage lines.
