DJ8939.The coordinates were established by GPS observations
DJ8939.and adjusted by the National Geodetic Survey in June 2019.
DJ8939
DJ8939.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DJ8939.been affixed to the stable North American Tectonic Plate.
DJ8939
DJ8939.The coordinates are valid at the epoch date displayed above
DJ8939.which is a decimal equivalence of Year/Month/Day.
DJ8939
DJ8939.Due to the release of the International GNSS Service (IGS) 2014
DJ8939.realization of the International Terrestrial Reference Frame of 2014
DJ8939.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DJ8939.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DJ8939.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DJ8939.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DJ8939.currently published epoch of 2010.00.
DJ8939
DJ8939.Additional information on MYCS2 is available at

DJ8939.Significant digits in the geoid height do not necessarily reflect accuracy.
DJ8939.GEOID18 height accuracy estimate available here.

DJ8939.The XYZ, and position/ellipsoidal ht. are equivalent.
DJ8939
DJ8939.The ellipsoidal height was determined by GPS observations
DJ8939.and is referenced to NAD 83.
