DL3073.The coordinates were established by GPS observations
DL3073.and adjusted by the National Geodetic Survey in June 2019.
DL3073
DL3073.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3073.been affixed to the stable North American Tectonic Plate.
DL3073
DL3073.The coordinates are valid at the epoch date displayed above
DL3073.which is a decimal equivalence of Year/Month/Day.
DL3073
DL3073.Due to the release of the International GNSS Service (IGS) 2014
DL3073.realization of the International Terrestrial Reference Frame of 2014
DL3073.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3073.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3073.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3073.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3073.currently published epoch of 2010.00.
DL3073
DL3073.Additional information on MYCS2 is available at
DL3073.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL3073.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3073.GEOID18 height accuracy estimate available here.

DL3073.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3073
DL3073.The ellipsoidal height was determined by GPS observations
DL3073.and is referenced to NAD 83.
