AH2494.The coordinates were established by GPS observations
AH2494.and adjusted by the National Geodetic Survey in June 2019.
AH2494
AH2494.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH2494.been affixed to the stable North American Tectonic Plate.
AH2494
AH2494.The coordinates are valid at the epoch date displayed above
AH2494.which is a decimal equivalence of Year/Month/Day.
AH2494
AH2494.Due to the release of the International GNSS Service (IGS) 2014
AH2494.realization of the International Terrestrial Reference Frame of 2014
AH2494.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH2494.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH2494.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH2494.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH2494.currently published epoch of 2010.00.
AH2494
AH2494.Additional information on MYCS2 is available at
AH2494.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AH2494.Significant digits in the geoid height do not necessarily reflect accuracy.
AH2494.GEOID12B height accuracy estimate available here.

AH2494.The PID for the CORS L1 Phase Center is AH2495.

AH2494.The XYZ, and position/ellipsoidal ht. are equivalent.
AH2494
AH2494.The ellipsoidal height was determined by GPS observations
AH2494.and is referenced to NAD 83.
