AH9962.The coordinates were established by GPS observations
AH9962.and adjusted by the National Geodetic Survey in June 2019.
AH9962
AH9962.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AH9962.been affixed to the stable North American Tectonic Plate.
AH9962
AH9962.The coordinates are valid at the epoch date displayed above
AH9962.which is a decimal equivalence of Year/Month/Day.
AH9962
AH9962.Due to the release of the International GNSS Service (IGS) 2014
AH9962.realization of the International Terrestrial Reference Frame of 2014
AH9962.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AH9962.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AH9962.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AH9962.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AH9962.currently published epoch of 2010.00.
AH9962
AH9962.Additional information on MYCS2 is available at
AH9962.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AH9962
AH9962.The orthometric height was determined by GPS observations and a
AH9962.high-resolution geoid model using precise GPS observation and
AH9962.processing techniques.
AH9962
AH9962.Significant digits in the geoid height do not necessarily reflect accuracy.
