To reach the tidal bench marks from Honolulu, take H-1 West and exit at the
"Hickam AFB/Pearl Harbor" off ramp.  Stay to the left and enter the main gate of
Hickam AFB. Proceed straight ahead, passing the flight line, and stay in the
left lane, which turns into Vickers Avenue, then proceed on Vickers Avenue until
it makes a sharp left turn, where its name chages to Fort Kam Street.  Instead
of turning left, proceed ahead through the main gate of Bishop Point NAVSTA, and
proceed for about 46 m (150 ft).  The bench marks are located along Fort Kam
Street and vicinity.  The tide station was located at the inshore end of pier
A3/A4.

Mean Sea Level (MSL) is a tidal datum determined over a 19-year National
Tidal Datum Epoch.  It pertains to local mean sea level and should not be
confused with any other fixed island datum.

This tide station location has a local island datum.  Island datums
are specific fixed geodetic datums whose elevation relationship to local MSL
and other tidal datums may not be consistent from one location to another.

The Vertical Mark Number (VM#) and PID# shown on the bench mark sheet are unique
identifiers for bench marks in the tidal and geodetic databases, respectively.
Each bench mark in either database has a single, unique VM# and/or PID# assigned.
Where both VM# and PID# are indicated, both tidal and geodetic elevations are
available for the bench mark listed. The NGS's Integrated Data Base (IDB PID)
provides geodetic datum based on traditionally leveled and bluebooked ties to
the National Spatial Reference System(NSRS) https://www.ngs.noaa.gov/datasheets/.
The NGS Online Positioning User Service (OPUS PID) provides geodetic datum based
on GPS position & tie it to the NSRS https://www.ngs.noaa.gov/OPUS/.
