GLOSSARY ENTRY (DERIVED FROM QUESTION BELOW)

Tech/Engineering - Surveying / surveying
Dutch term or phrase: NAP-bout
Another surveying term. Here's a nice definition found with a quick web search (unfortunately my own text leaves me in the dark a lot): "Een NAP-bout is een hoogtemeetpunt aan de hand waarvan de hoogte ten opzichte van het Normaal Amsterdams Peil (NAP) wordt bepaald."

I've concocted "ordnance datum reference stud" myself, but the question is, what is the real name of such a marker in English?

Thinking about it Chris, your \"stud\" wasn\'t far out. The above describes a metal \"plate\", nowadays they tend to use a thing that resembles a metal stud. However, the technical name for this orientation aid is a \"bench mark\". It is actually used as a reference point. e.g. On drawings you may see +3 metres, which indicates that the point referred to is at a level 3 metres higher than the \"bench mark\".

As a matter of interest, when you\'ve been walking in the country with your best girl at your side, you may have noticed a block of stone with what looks like an arrow carved into it. This was the old fashioned way of installing a bench mark. So now you know.-))

David, you are a genius! Thanks.

BTW, I found this nice definition of "bench mark" which tends to make "MSL" superfluous in the translation, especially as the text is for topgraphical experts.

"All bench mark heights are given in relationship to the one national datum plane which in general is the mean sea level (MSL)."

And that's exactly what this NAP-bout is: a marker at a known height above sea level!

Mean Sea Level (MSL)


Explanation:
Mean Sea Level; Mean Lower Low Water, which legally determines the nation's shoreline; and Mean High Water, which determines the boundary between some state and private lands, and is the basis for defining the limits of the Nation's Exclusive Economic Zone and international High Seas.

Engineering and construction firms use water level data to wisely plan future designs and operations

after re-reading the question, BM-stud or bolt might be a suitable answer to NAP-bout (bout in this case meaning bolt as in bolt and nut or \"bout en moer\")

So David is right

On second thought, MSL-benchmark might be better

agree  eldira: after re-reading the question, "benchmark" (B.M.) is the answer to NAP-bout. A bench mark can be a concrete base in which an iron bar is fixed - www.fao.org/docrep/R4082E/r4082e04.htm

agree  AllisonK (X): on benchmark as well, only the NAP has to be worked in there too, doesn't it? And MSL is the correct answer for NAP...
