DG7402.The coordinates were established by GPS observations
DG7402.and adjusted by the National Geodetic Survey in June 2019.
DG7402
DG7402.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG7402.been affixed to the stable North American Tectonic Plate.
DG7402
DG7402.The coordinates are valid at the epoch date displayed above
DG7402.which is a decimal equivalence of Year/Month/Day.
DG7402
DG7402.Due to the release of the International GNSS Service (IGS) 2014
DG7402.realization of the International Terrestrial Reference Frame of 2014
DG7402.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG7402.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG7402.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG7402.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG7402.currently published epoch of 2010.00.
DG7402
DG7402.Additional information on MYCS2 is available at
DG7402.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG7402
DG7402.The orthometric height was determined by GPS observations and a
DG7402.high-resolution geoid model using precise GPS observation and
DG7402.processing techniques.
DG7402
DG7402.Significant digits in the geoid height do not necessarily reflect accuracy.
DG7402.GEOID18 height accuracy estimate available here.
DG7402
DG7402.The PID for the CORS L1 Phase Center is DS2716.

DG7402.The XYZ, and position/ellipsoidal ht. are equivalent.
DG7402
DG7402.The ellipsoidal height was determined by GPS observations
DG7402.and is referenced to NAD 83.
