AF9670.The coordinates were established by GPS observations
AF9670.and adjusted by the National Geodetic Survey in June 2019.
AF9670
AF9670.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AF9670.been affixed to the stable North American Tectonic Plate.
AF9670
AF9670.The coordinates are valid at the epoch date displayed above
AF9670.which is a decimal equivalence of Year/Month/Day.
AF9670
AF9670.Due to the release of the International GNSS Service (IGS) 2014
AF9670.realization of the International Terrestrial Reference Frame of 2014
AF9670.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AF9670.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AF9670.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AF9670.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AF9670.currently published epoch of 2010.00.
AF9670
AF9670.Additional information on MYCS2 is available at
AF9670.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AF9670
AF9670.The orthometric height was determined by GPS observations and a
AF9670.high-resolution geoid model using precise GPS observation and
AF9670.processing techniques.
AF9670
AF9670.Significant digits in the geoid height do not necessarily reflect accuracy.
AF9670.GEOID18 height accuracy estimate available here.
