DH8997.The coordinates were established by GPS observations
DH8997.and adjusted by the National Geodetic Survey in June 2019.
DH8997
DH8997.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH8997.been affixed to the stable North American Tectonic Plate.
DH8997
DH8997.The coordinates are valid at the epoch date displayed above
DH8997.which is a decimal equivalence of Year/Month/Day.
DH8997
DH8997.Due to the release of the International GNSS Service (IGS) 2014
DH8997.realization of the International Terrestrial Reference Frame of 2014
DH8997.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH8997.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH8997.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH8997.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH8997.currently published epoch of 2010.00.
DH8997
DH8997.Additional information on MYCS2 is available at
DH8997.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH8997
DH8997.The orthometric height was determined by GPS observations and a
DH8997.high-resolution geoid model using precise GPS observation and
DH8997.processing techniques.
DH8997
DH8997.Significant digits in the geoid height do not necessarily reflect accuracy.
DH8997.GEOID18 height accuracy estimate available here.
DH8997
DH8997.The PID for the CORS L1 Phase Center is DR7717.

DH8997.Click photographs - Photos may exist for this station.
DH8997
DH8997.The XYZ, and position/ellipsoidal ht. are equivalent.
DH8997
DH8997.The ellipsoidal height was determined by GPS observations
DH8997.and is referenced to NAD 83.
