DN7554.The coordinates were established by GPS observations
DN7554.and adjusted by the National Geodetic Survey in June 2019.
DN7554
DN7554.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN7554.been affixed to the stable North American Tectonic Plate.
DN7554
DN7554.The coordinates are valid at the epoch date displayed above
DN7554.which is a decimal equivalence of Year/Month/Day.
DN7554
DN7554.Due to the release of the International GNSS Service (IGS) 2014
DN7554.realization of the International Terrestrial Reference Frame of 2014
DN7554.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN7554.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN7554.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN7554.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN7554.currently published epoch of 2010.00.
DN7554
DN7554.Additional information on MYCS2 is available at
DN7554.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN7554.Significant digits in the geoid height do not necessarily reflect accuracy.
DN7554.GEOID18 height accuracy estimate available here.

DN7554.The XYZ, and position/ellipsoidal ht. are equivalent.
DN7554
DN7554.The ellipsoidal height was determined by GPS observations
DN7554.and is referenced to NAD 83.
