I don't exactly understand the definition of a "Street Lamp". iD doesn't offer any guidance. Is the Street Lamp, supported by a "pole" which is on the "ground", or is the "ground" what supports the street lamp which is a light on a pole? The documentation says,
So the Street Lamp includes a pole, and can never be supported by a pole? asked 28 Sep '22, 22:10  Evan Carroll edited 28 Sep '22, 22:11 |

You mean to that which the pole is mounted. The option for lamp_mount is "ground" that can't be how the lamp is mounted on the pole.
No, I double-checked the wiki articles to make sure what I stated was correct.
lamp_mount=groundwould be non-sensical, because it's saying the lamp is mounted on the pole/wall/etc. using a "ground" attachment method. You usesupport=*to describe how the lamp is supported (ie.pole,wall, orgroundif it's right in the ground), and uselamp_mount=*to describe how the lamp is mounted on that support (ie.bent_mast,straight_mast,suspended, etc.).I'd be curious where you read that text saying "
lamp_mount=*is used describe how ahighway=street_lampis supported", because that isn't correct.@alester "I'd be curious where you read that text" - it is on the wiki page for key lamp_mount: https://wiki.openstreetmap.org/wiki/Key:lamp_mount
However, "ground" is not listed as an option there so I'm not sure if "The option for lamp_mount is ground" refers to a different wiki page or some other document. There are about 700 uses worldwide of lamp_mount=ground according to taginfo so maybe it appears is some software that takes suggested values from taginfo.
