DI7534.The coordinates were established by GPS observations
DI7534.and adjusted by the National Geodetic Survey in June 2019.
DI7534
DI7534.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI7534.been affixed to the stable North American Tectonic Plate.
DI7534
DI7534.The coordinates are valid at the epoch date displayed above
DI7534.which is a decimal equivalence of Year/Month/Day.
DI7534
DI7534.Due to the release of the International GNSS Service (IGS) 2014
DI7534.realization of the International Terrestrial Reference Frame of 2014
DI7534.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI7534.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI7534.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI7534.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI7534.currently published epoch of 2010.00.
DI7534
DI7534.Additional information on MYCS2 is available at
DI7534.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI7534.Significant digits in the geoid height do not necessarily reflect accuracy.
DI7534.GEOID18 height accuracy estimate available here.

DI7534.The XYZ, and position/ellipsoidal ht. are equivalent.
DI7534
DI7534.The ellipsoidal height was determined by GPS observations
DI7534.and is referenced to NAD 83.
