Height bolts or NAP bolts

A height bolt is a metal nail that is installed in a building or work of art (bridge/viaduct). On the basis of a height bolt, heights relative to Normal Amsterdam Level (NAP) can be determined for buildings, infrastructure and water management. The data contains the locations and heights of the bolts in Eindhoven.Note: A check should always be carried out by leveling between two height bolts. This is to prevent an incorrect height bolt or height from being maintained. The spread is such that there is a height bolt within 500 meters. The accuracy of the NAP height is ± 3 mm.
