I just observed recently that Open Street Map is showing Transmission line, Transmission line structures, and Substation locations. As well as Voltage for those lines.
Is that legal from a Homeland Security point of view?
We only just noticed it because we never use that as a base map but I turned it on the other day.
There is an indication that one of our lines was added 12 years ago. Now we never give out our data without a date share agreement. NERC. And 12 years ago there were very few we had shared it with in a digital format.
