DJ9550.The coordinates were established by GPS observations
DJ9550.and adjusted by the National Geodetic Survey in June 2019.
DJ9550
DJ9550.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DJ9550.been affixed to the stable North American Tectonic Plate.
DJ9550
DJ9550.The coordinates are valid at the epoch date displayed above
DJ9550.which is a decimal equivalence of Year/Month/Day.
DJ9550
DJ9550.Due to the release of the International GNSS Service (IGS) 2014
DJ9550.realization of the International Terrestrial Reference Frame of 2014
DJ9550.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DJ9550.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DJ9550.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DJ9550.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DJ9550.currently published epoch of 2010.00.
DJ9550
DJ9550.Additional information on MYCS2 is available at
DJ9550.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DJ9550.Significant digits in the geoid height do not necessarily reflect accuracy.
DJ9550.GEOID18 height accuracy estimate available here.

DJ9550.The XYZ, and position/ellipsoidal ht. are equivalent.
DJ9550
DJ9550.The ellipsoidal height was determined by GPS observations
DJ9550.and is referenced to NAD 83.
