DH7123.The coordinates were established by GPS observations
DH7123.and adjusted by the National Geodetic Survey in June 2019.
DH7123
DH7123.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH7123.been affixed to the stable North American Tectonic Plate.
DH7123
DH7123.The coordinates are valid at the epoch date displayed above
DH7123.which is a decimal equivalence of Year/Month/Day.
DH7123
DH7123.Due to the release of the International GNSS Service (IGS) 2014
DH7123.realization of the International Terrestrial Reference Frame of 2014
DH7123.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH7123.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH7123.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH7123.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH7123.currently published epoch of 2010.00.
DH7123
DH7123.Additional information on MYCS2 is available at
DH7123.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH7123
DH7123.The orthometric height was determined by GPS observations and a
DH7123.high-resolution geoid model using precise GPS observation and
DH7123.processing techniques.
DH7123
DH7123.Significant digits in the geoid height do not necessarily reflect accuracy.
DH7123.GEOID18 height accuracy estimate available here.

DH7123.The PID for the CORS L1 Phase Center is DH7124.

DH7123.The XYZ, and position/ellipsoidal ht. are equivalent.
DH7123
DH7123.The ellipsoidal height was determined by GPS observations
DH7123.and is referenced to NAD 83.
