Just curious where OSM gets its data for US power grids (stations/substations/powerlines/etc). I'm researching power stations in my area, and am curious where the authoritative source is - I'd also like to help keep the power grid data up to date, and would like to know where to check. asked 17 May '17, 16:16  ParkerKK |
One Answer:
A lot of it is just from imagery (many features have no further information beyond what is observable in imagery). I think a lot of people input information based on their understanding of the power grid and from sources like permits. The EIA has a pretty massive amount of data on US infrastructure: https://www.eia.gov/state/maps.php A review of which layers are suitable as OSM sources (appropriately licensed and so on) would be a useful thing: answered 17 May '17, 17:08  maxerickson Quite a lot of power lines would have come in originally with TIGER data too.
