Dutch NAP

No, I am not talking about having a rest, but about the "Normaal Amsterdams Peil" (NAP) or Amsterdam Ordnance Datum, a national Dutch levelling reference system. It is the reference to measure the level of a place in the coutry compared to the average sea level. Measuring the sea level dates back as far as 1683 and was started by the mayor from Amsterdam Hudde. I took the picture in Scheveningen harbour. Whenever some storming weather is expected, the NAP level will be carefully monitored.

If you live in Holland, just insert your postcode here to know at which level you live compared to sea water level.
