If they are pillars then that’s fine. If a more general term is required how
about geodesy = station or survey_station

This works but not sure a namespace is really required. Perhaps also
consider geodetic_network=

Same as above. Perhaps geogdetic_ref=

But anyway, it's not that critical to get it perfect. The tags can always be
mapped to other tags later (eg for a STAGS type approach). Whichever you or
