AI7660.The coordinates were established by GPS observations
AI7660.and adjusted by the National Geodetic Survey in June 2019.
AI7660
AI7660.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI7660.been affixed to the stable North American Tectonic Plate.
AI7660
AI7660.The coordinates are valid at the epoch date displayed above
AI7660.which is a decimal equivalence of Year/Month/Day.
AI7660
AI7660.Due to the release of the International GNSS Service (IGS) 2014
AI7660.realization of the International Terrestrial Reference Frame of 2014
AI7660.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI7660.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI7660.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI7660.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI7660.currently published epoch of 2010.00.
AI7660
AI7660.Additional information on MYCS2 is available at

AI7660.The XYZ, and position/ellipsoidal ht. are equivalent.
AI7660
AI7660.The ellipsoidal height was determined by GPS observations
AI7660.and is referenced to NAD 83.
