AI3287.The coordinates were established by GPS observations
AI3287.and adjusted by the National Geodetic Survey in June 2019.
AI3287
AI3287.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI3287.been affixed to the stable North American Tectonic Plate.
AI3287
AI3287.The coordinates are valid at the epoch date displayed above
AI3287.which is a decimal equivalence of Year/Month/Day.
AI3287
AI3287.Due to the release of the International GNSS Service (IGS) 2014
AI3287.realization of the International Terrestrial Reference Frame of 2014
AI3287.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI3287.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI3287.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI3287.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI3287.currently published epoch of 2010.00.
AI3287
AI3287.Additional information on MYCS2 is available at
AI3287.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AI3287.The XYZ, and position/ellipsoidal ht. are equivalent.
AI3287
AI3287.The ellipsoidal height was determined by GPS observations
AI3287.and is referenced to NAD 83.
