AF9702.The coordinates were established by GPS observations
AF9702.and adjusted by the National Geodetic Survey in September 2022.
AF9702
AF9702.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9702.been affixed to the stable North American Tectonic Plate.
AF9702
AF9702.The coordinates are valid at the epoch date displayed above
AF9702.which is a decimal equivalence of Year/Month/Day.
AF9702
AF9702.Due to the release of the International GNSS Service (IGS) 2014
AF9702.realization of the International Terrestrial Reference Frame of 2014
AF9702.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9702.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9702.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9702.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9702.currently published epoch of 2010.00.
AF9702
AF9702.Additional information on MYCS2 is available at
