The 'tidal bench mark survey' is designed to manage the tidal bench mark laid under the ground based on tidal observation in order to set standards for measuring water depths and heights during hydrographic surveys. The purpose is to survey heights and longitude and latitude coordinates from base levels (datum level and average sea level) by means of tidal observations.
The tidal bench mark should be installed in natural rocks on firm foundation or without subsidence, or on the ground. Each station manages three laid marks including one as a reference point.

When a tidal bench mark is installed or results have changed, these facts are provided for users by means of the tide table of our web page.
