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.

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/.
