AF9574.The coordinates were established by GPS observations
AF9574.and adjusted by the National Geodetic Survey in June 2019.
AF9574
AF9574.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9574.been affixed to the stable North American Tectonic Plate.
AF9574
AF9574.The coordinates are valid at the epoch date displayed above
AF9574.which is a decimal equivalence of Year/Month/Day.
AF9574
AF9574.Due to the release of the International GNSS Service (IGS) 2014
AF9574.realization of the International Terrestrial Reference Frame of 2014
AF9574.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9574.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9574.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9574.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9574.currently published epoch of 2010.00.
AF9574
AF9574.Additional information on MYCS2 is available at
AF9574.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AF9574.** This station is in an area of known vertical motion. If an
AF9574.** orthometric height was ever established but is not available
AF9574.** in the current survey control section, the orthometric height
AF9574.** is considered suspect. Suspect heights are available in the
AF9574.** superseded section only if requested.
AF9574
AF9574.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9574.GEOID18 height accuracy estimate available here.

AF9574.The PID for the CORS L1 Phase Center is AB8531.

AF9574.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9574
AF9574.The ellipsoidal height was determined by GPS observations
AF9574.and is referenced to NAD 83.
