AF9661.The coordinates were established by GPS observations
AF9661.and adjusted by the National Geodetic Survey in June 2019.
AF9661
AF9661.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9661.been affixed to the stable North American Tectonic Plate.
AF9661
AF9661.The coordinates are valid at the epoch date displayed above
AF9661.which is a decimal equivalence of Year/Month/Day.
AF9661
AF9661.Due to the release of the International GNSS Service (IGS) 2014
AF9661.realization of the International Terrestrial Reference Frame of 2014
AF9661.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9661.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9661.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9661.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9661.currently published epoch of 2010.00.
AF9661
AF9661.Additional information on MYCS2 is available at
AF9661.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AF9661.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9661.GEOID18 height accuracy estimate available here.

AF9661.Click photographs - Photos may exist for this station.
AF9661
AF9661.The XYZ, and position/ellipsoidal ht. are equivalent.
AF9661
AF9661.The ellipsoidal height was determined by GPS observations
AF9661.and is referenced to NAD 83.
