AI7445.The coordinates were established by GPS observations
AI7445.and adjusted by the National Geodetic Survey in June 2019.
AI7445
AI7445.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI7445.been affixed to the stable North American Tectonic Plate.
AI7445
AI7445.The coordinates are valid at the epoch date displayed above
AI7445.which is a decimal equivalence of Year/Month/Day.
AI7445
AI7445.Due to the release of the International GNSS Service (IGS) 2014
AI7445.realization of the International Terrestrial Reference Frame of 2014
AI7445.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI7445.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI7445.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI7445.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI7445.currently published epoch of 2010.00.
AI7445
AI7445.Additional information on MYCS2 is available at
AI7445.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AI7445
AI7445.The orthometric height was determined by GPS observations and a
AI7445.high-resolution geoid model using precise GPS observation and
AI7445.processing techniques.
AI7445
AI7445.Significant digits in the geoid height do not necessarily reflect accuracy.
AI7445.GEOID18 height accuracy estimate available here.
AI7445
AI7445.The PID for the CORS L1 Phase Center is AI7446.

AI7445.The XYZ, and position/ellipsoidal ht. are equivalent.
AI7445
AI7445.The ellipsoidal height was determined by GPS observations
AI7445.and is referenced to NAD 83.
