 AF9654.The coordinates were established by GPS observations
 AF9654.and adjusted by the National Geodetic Survey in June 2019.
 AF9654
 AF9654.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AF9654.been affixed to the stable North American Tectonic Plate. 
 AF9654
 AF9654.The coordinates are valid at the epoch date displayed above
 AF9654.which is a decimal equivalence of Year/Month/Day.
 AF9654
 AF9654.Due to the release of the International GNSS Service (IGS) 2014
 AF9654.realization of the International Terrestrial Reference Frame of 2014
 AF9654.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
 AF9654.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
 AF9654.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
 AF9654.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
 AF9654.currently published epoch of 2010.00.
 AF9654
 AF9654.Additional information on MYCS2 is available at
 AF9654.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
 AF9654
 AF9654.The orthometric height was determined by GPS observations and a
 AF9654.high-resolution geoid model using precise GPS observation and
 AF9654.processing techniques.
 AF9654
 AF9654.Significant digits in the geoid height do not necessarily reflect accuracy.
 AF9654.GEOID18 height accuracy estimate available here.
 AF9654
 AF9654.The PID for the CORS L1 Phase Center is AE4426.

 AF9654.Click photographs - Photos may exist for this station.
 AF9654
 AF9654.The XYZ, and position/ellipsoidal ht. are equivalent.
 AF9654
 AF9654.The ellipsoidal height was determined by GPS observations
 AF9654.and is referenced to NAD 83.
 AF9654
 AF9654. The following values were computed from the NAD 83(2011) position.
