DG8219.The coordinates were established by GPS observations
DG8219.and adjusted by the National Geodetic Survey in June 2019.
DG8219
DG8219.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG8219.been affixed to the stable North American Tectonic Plate.
DG8219
DG8219.The coordinates are valid at the epoch date displayed above
DG8219.which is a decimal equivalence of Year/Month/Day.
DG8219
DG8219.Due to the release of the International GNSS Service (IGS) 2014
DG8219.realization of the International Terrestrial Reference Frame of 2014
DG8219.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG8219.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG8219.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG8219.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG8219.currently published epoch of 2010.00.
DG8219
DG8219.Additional information on MYCS2 is available at
DG8219.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG8219
DG8219.The orthometric height was determined by GPS observations and a
DG8219.high-resolution geoid model using precise GPS observation and
DG8219.processing techniques.
DG8219
DG8219.Significant digits in the geoid height do not necessarily reflect accuracy.
DG8219.GEOID18 height accuracy estimate available here.
DG8219
DG8219.The PID for the CORS L1 Phase Center is DG8220.

DG8219
DG8219.The XYZ, and position/ellipsoidal ht. are equivalent.
DG8219
DG8219.The ellipsoidal height was determined by GPS observations
DG8219.and is referenced to NAD 83.
