OpenStreetMap supports annotating poles and theirs cables. It's common for power lines (local and long distance). There are also annotations for communication lines (https://wiki.openstreetmap.org/wiki/Tag:communication%3Dline). There are also public and proprietary "aviation obstacle" databases across the world. |
