DG7018.The coordinates were established by GPS observations
DG7018.and adjusted by the National Geodetic Survey in June 2019.
DG7018
DG7018.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG7018.been affixed to the stable North American Tectonic Plate.
DG7018
DG7018.The coordinates are valid at the epoch date displayed above
DG7018.which is a decimal equivalence of Year/Month/Day.
DG7018
DG7018.Due to the release of the International GNSS Service (IGS) 2014
DG7018.realization of the International Terrestrial Reference Frame of 2014
DG7018.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG7018.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG7018.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG7018.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG7018.currently published epoch of 2010.00.
DG7018
DG7018.Additional information on MYCS2 is available at
DG7018.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG7018
DG7018.The orthometric height was determined by GPS observations and a
DG7018.high-resolution geoid model using precise GPS observation and
DG7018.processing techniques.
DG7018
DG7018.Significant digits in the geoid height do not necessarily reflect accuracy.
DG7018.GEOID18 height accuracy estimate available here.
DG7018
DG7018.The PID for the CORS L1 Phase Center is DG7019.

DG7018
DG7018.The XYZ, and position/ellipsoidal ht. are equivalent.
DG7018
DG7018.The ellipsoidal height was determined by GPS observations
DG7018.and is referenced to NAD 83.
