AM7026.The coordinates were established by GPS observations
AM7026.and adjusted by the National Geodetic Survey in June 2019.
AM7026
AM7026.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AM7026.been affixed to the stable North American Tectonic Plate.
AM7026
AM7026.The coordinates are valid at the epoch date displayed above
AM7026.which is a decimal equivalence of Year/Month/Day.
AM7026
AM7026.Due to the release of the International GNSS Service (IGS) 2014
AM7026.realization of the International Terrestrial Reference Frame of 2014
AM7026.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AM7026.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AM7026.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AM7026.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AM7026.currently published epoch of 2010.00.
AM7026
AM7026.Additional information on MYCS2 is available at
AM7026.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AM7026.Significant digits in the geoid height do not necessarily reflect accuracy.
AM7026.GEOID18 height accuracy estimate available here.

AM7026.The XYZ, and position/ellipsoidal ht. are equivalent.
AM7026
AM7026.The ellipsoidal height was determined by GPS observations
AM7026.and is referenced to NAD 83.
