DL6314.The coordinates were established by GPS observations
DL6314.and adjusted by the National Geodetic Survey in June 2019.
DL6314
DL6314.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6314.been affixed to the stable North American Tectonic Plate.
DL6314
DL6314.The coordinates are valid at the epoch date displayed above
DL6314.which is a decimal equivalence of Year/Month/Day.
DL6314
DL6314.Due to the release of the International GNSS Service (IGS) 2014
DL6314.realization of the International Terrestrial Reference Frame of 2014
DL6314.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6314.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6314.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6314.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6314.currently published epoch of 2010.00.
DL6314
DL6314.Additional information on MYCS2 is available at
DL6314.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL6314.Significant digits in the geoid height do not necessarily reflect accuracy.
DL6314.GEOID18 height accuracy estimate available here.

DL6314.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6314
DL6314.The ellipsoidal height was determined by GPS observations
DL6314.and is referenced to NAD 83.
