AH6714.The coordinates were established by GPS observations
AH6714.and adjusted by the National Geodetic Survey in June 2019.
AH6714
AH6714.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH6714.been affixed to the stable North American Tectonic Plate.
AH6714
AH6714.The coordinates are valid at the epoch date displayed above
AH6714.which is a decimal equivalence of Year/Month/Day.
AH6714
AH6714.Due to the release of the International GNSS Service (IGS) 2014
AH6714.realization of the International Terrestrial Reference Frame of 2014
AH6714.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH6714.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH6714.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH6714.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH6714.currently published epoch of 2010.00.
AH6714
AH6714.Additional information on MYCS2 is available at
AH6714.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AH6714
AH6714.The orthometric height was determined by GPS observations and a
AH6714.high-resolution geoid model using precise GPS observation and
AH6714.processing techniques.
AH6714
AH6714.Significant digits in the geoid height do not necessarily reflect accuracy.
AH6714.GEOID18 height accuracy estimate available here.
AH6714
AH6714.The PID for the CORS L1 Phase Center is DI3466.

AH6714
AH6714.The XYZ, and position/ellipsoidal ht. are equivalent.
AH6714
AH6714.The ellipsoidal height was determined by GPS observations
AH6714.and is referenced to NAD 83.
