AF9530.The coordinates were established by GPS observations
AF9530.and adjusted by the National Geodetic Survey in June 2019.
AF9530
AF9530.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9530.been affixed to the stable North American Tectonic Plate.
AF9530
AF9530.The coordinates are valid at the epoch date displayed above
AF9530.which is a decimal equivalence of Year/Month/Day.
AF9530
AF9530.Due to the release of the International GNSS Service (IGS) 2014
AF9530.realization of the International Terrestrial Reference Frame of 2014
AF9530.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9530.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9530.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9530.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9530.currently published epoch of 2010.00.
AF9530
AF9530.Additional information on MYCS2 is available at
AF9530.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AF9530.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9530.GEOID12B height accuracy estimate available here.

AF9530
AF9530.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9530
AF9530.The ellipsoidal height was determined by GPS observations
AF9530.and is referenced to NAD 83.
