AF9678.The coordinates were established by GPS observations
AF9678.and adjusted by the National Geodetic Survey in June 2019.
AF9678
AF9678.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9678.been affixed to the stable North American Tectonic Plate.
AF9678
AF9678.The coordinates are valid at the epoch date displayed above
AF9678.which is a decimal equivalence of Year/Month/Day.
AF9678
AF9678.Due to the release of the International GNSS Service (IGS) 2014
AF9678.realization of the International Terrestrial Reference Frame of 2014
AF9678.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9678.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9678.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9678.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9678.currently published epoch of 2010.00.
AF9678
AF9678.Additional information on MYCS2 is available at
AF9678.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AF9678.Significant digits in the geoid height do not necessarily reflect accuracy.

AF9678.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9678
AF9678.The ellipsoidal height was determined by GPS observations
AF9678.and is referenced to NAD 83.
