DL7716.The coordinates were established by GPS observations
DL7716.and adjusted by the National Geodetic Survey in June 2019.
DL7716
DL7716.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7716.been affixed to the stable North American Tectonic Plate.
DL7716
DL7716.The coordinates are valid at the epoch date displayed above
DL7716.which is a decimal equivalence of Year/Month/Day.
DL7716
DL7716.Due to the release of the International GNSS Service (IGS) 2014
DL7716.realization of the International Terrestrial Reference Frame of 2014
DL7716.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7716.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7716.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7716.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7716.currently published epoch of 2010.00.
DL7716
DL7716.Additional information on MYCS2 is available at

DL7716.Significant digits in the geoid height do not necessarily reflect accuracy.
DL7716.GEOID18 height accuracy estimate available here.

DL7716.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7716
DL7716.The ellipsoidal height was determined by GPS observations
DL7716.and is referenced to NAD 83.
