AF9646.The coordinates were established by GPS observations
AF9646.and adjusted by the National Geodetic Survey in May 2020.
AF9646
AF9646.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9646.been affixed to the stable North American Tectonic Plate.
AF9646
AF9646.The coordinates are valid at the epoch date displayed above
AF9646.which is a decimal equivalence of Year/Month/Day.
AF9646
AF9646.Due to the release of the International GNSS Service (IGS) 2014
AF9646.realization of the International Terrestrial Reference Frame of 2014
AF9646.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9646.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9646.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9646.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9646.currently published epoch of 2010.00.
AF9646
AF9646.Additional information on MYCS2 is available at
AF9646.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AF9646.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9646
AF9646.The ellipsoidal height was determined by GPS observations
AF9646.and is referenced to NAD 83.
