To reach the tidal bench marks, from the Lihue Airport take a left on Ahukini
Road (State Highway 57) and then go south on Kapule Highway (State Highway 51),
then proceed 2.4 km (1.5 mi) and turn south on Rice Street.  Proceed 1.3 km (0.8
mi) and turn west on Waapa Road, then proceed 0.3 km (0.2 mi) to the gate to
Pier # 2, and turn south through the gate to the Pier #2 Warehouse.  The bench
marks are located along Waapa Road and Kapule Highway (State Highway 51) in the
vicinity of Pier # 2.  The tide station is located in the SW corner of the
warehouse.

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/.
