AI7658.The coordinates were established by GPS observations
AI7658.and adjusted by the National Geodetic Survey in June 2019.
AI7658
AI7658.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI7658.been affixed to the stable North American Tectonic Plate.
AI7658
AI7658.The coordinates are valid at the epoch date displayed above
AI7658.which is a decimal equivalence of Year/Month/Day.
AI7658
AI7658.Due to the release of the International GNSS Service (IGS) 2014
AI7658.realization of the International Terrestrial Reference Frame of 2014
AI7658.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI7658.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI7658.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI7658.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI7658.currently published epoch of 2010.00.
AI7658
AI7658.Additional information on MYCS2 is available at
AI7658.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AI7658
AI7658.The orthometric height was determined by GPS observations and a
AI7658.high-resolution geoid model using precise GPS observation and
AI7658.processing techniques.
AI7658
AI7658.Significant digits in the geoid height do not necessarily reflect accuracy.
AI7658.GEOID18 height accuracy estimate available here.
AI7658
AI7658.The PID for the CORS L1 Phase Center is AI7659.

AI7658.The XYZ, and position/ellipsoidal ht. are equivalent.
AI7658
AI7658.The ellipsoidal height was determined by GPS observations
AI7658.and is referenced to NAD 83.
