DF8972.The coordinates were established by GPS observations
DF8972.and adjusted by the National Geodetic Survey in June 2019.
DF8972
DF8972.NAD 83(PA11) refers to NAD 83 coordinates where the reference frame has
DF8972.been affixed to the stable Pacific Tectonic Plate.
DF8972
DF8972.The coordinates are valid at the epoch date displayed above
DF8972.which is a decimal equivalence of Year/Month/Day.
DF8972
DF8972.Due to the release of the International GNSS Service (IGS) 2014
DF8972.realization of the International Terrestrial Reference Frame of 2014
DF8972.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8972.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8972.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8972.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8972.currently published epoch of 2010.00.
DF8972
DF8972.Additional information on MYCS2 is available at
DF8972.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF8972
DF8972.The orthometric height was determined by GPS observations and a
DF8972.high-resolution geoid model using precise GPS observation and
DF8972.processing techniques.
DF8972
DF8972.Significant digits in the geoid height do not necessarily reflect accuracy.
DF8972.GEOID12B height accuracy estimate available here.
DF8972
DF8972.The PID for the CORS L1 Phase Center is DI9188.

DF8972.Click photographs - Photos may exist for this station.
DF8972
DF8972.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8972
DF8972.The ellipsoidal height was determined by GPS observations
DF8972.and is referenced to NAD 83.
