AI6959.The coordinates were established by GPS observations
AI6959.and adjusted by the National Geodetic Survey in June 2019.
AI6959
AI6959.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI6959.been affixed to the stable North American Tectonic Plate.
AI6959
AI6959.The coordinates are valid at the epoch date displayed above
AI6959.which is a decimal equivalence of Year/Month/Day.
AI6959
AI6959.Due to the release of the International GNSS Service (IGS) 2014
AI6959.realization of the International Terrestrial Reference Frame of 2014
AI6959.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI6959.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI6959.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI6959.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI6959.currently published epoch of 2010.00.
AI6959
AI6959.Additional information on MYCS2 is available at

AI6959.The XYZ, and position/ellipsoidal ht. are equivalent.
AI6959
AI6959.The ellipsoidal height was determined by GPS observations
AI6959.and is referenced to NAD 83.
