While they maybe 'ordnance survey points' where you are, it the rest of 
the world it would be more incisive to drop "ordnance" leaving 'survey 
points'.

Err "usually chiselled in stone with its typical horizontal bar and 
arrow below on vertical surfaces, dot with arrow below on horizontal 
surfaces."

I think that may be the usually case there.. what about elsewhere? Try 
to use the local things as examples rather than a strict definition?


 From https://en.wikipedia.org/wiki/Benchmark_(surveying)

It looks like the fundamental thing about them is the precise height of 
the point. I think that is the thing that needs to be stated in the 
definition?



Thank you, it will be nice to have some organization on survey_point=* !


Note:

I assume that the purpose of the survey point is what is trying to be 
tagged.

Others may have used survey_point=* for the physical structure or 
something else.

Perhaps a more specific key to get away from the mess?


survey_point:function=benchmark/trig_point/*

or

survey_point:structure=hexagonal_bolt/marked_stone/*


???
