DL3520.The coordinates were established by GPS observations
DL3520.and adjusted by the National Geodetic Survey in June 2019.
DL3520
DL3520.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3520.been affixed to the stable North American Tectonic Plate.
DL3520
DL3520.The coordinates are valid at the epoch date displayed above
DL3520.which is a decimal equivalence of Year/Month/Day.
DL3520
DL3520.Due to the release of the International GNSS Service (IGS) 2014
DL3520.realization of the International Terrestrial Reference Frame of 2014
DL3520.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3520.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3520.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3520.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3520.currently published epoch of 2010.00.
DL3520
DL3520.Additional information on MYCS2 is available at
DL3520.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL3520.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3520.GEOID18 height accuracy estimate available here.

DL3520.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3520
DL3520.The ellipsoidal height was determined by GPS observations
DL3520.and is referenced to NAD 83.
