How to Map

Nodes can be used for small substations. Areas are better for larger ones using aerial photography to identify their extent. Substations can vary in size from small little buildings the size of a garden shed to much larger installations to size of many football fields.

Associated tags:

• name=* The name of the facility
• operator=* The name of the company operating the substation.
• voltage=* The highest voltage of operation within the facility

Map representation

• area: This is an industrial type area, so something that ties win with the colour for industrial landuse, but darker area
• node: Some sort of symbol that prompts thoughts of electricity. A lightning flash, maybe?
