In the UK, the location of major transmission lines and substations is freely available on the National Grid website (well, it's under a restrictive license but that's not going to stop an attacker): https://www.nationalgrid.com/electricity-transmission/network-and-infrastructure/network-route-maps The location of major distribution substations is openly published by all the electricity distribution network operators in the UK. Some of them now openly publish highly detailed data on their networks. This approach is increasingly common across Europe - if anything, the UK is lagging behind the rest of Europe. In the USA, the Department for Homeland Security publishes similar data on substations and transmission lines (it's not as accurate) along with a whole lot more geospatial data on critical infrastructure: https://hifld-geoplatform.opendata.arcgis.com/ It's clear that all these countries have accepted that security by obscurity doesn't work - transmission substations and transmission lines are extremely obvious and would be very straightforward to identify from aerial imagery. -- Russ Garrett r...@garrett.co.uk _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
