AI8826.The coordinates were established by GPS observations
AI8826.and adjusted by the National Geodetic Survey in June 2019.
AI8826
AI8826.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AI8826.been affixed to the stable North American Tectonic Plate.
AI8826
AI8826.The coordinates are valid at the epoch date displayed above
AI8826.which is a decimal equivalence of Year/Month/Day.
AI8826
AI8826.Due to the release of the International GNSS Service (IGS) 2014
AI8826.realization of the International Terrestrial Reference Frame of 2014
AI8826.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AI8826.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AI8826.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AI8826.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AI8826.currently published epoch of 2010.00.
AI8826
AI8826.Additional information on MYCS2 is available at
AI8826.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AI8826
AI8826.The orthometric height was determined by GPS observations and a
AI8826.high-resolution geoid model using precise GPS observation and
AI8826.processing techniques.
AI8826
AI8826.Significant digits in the geoid height do not necessarily reflect accuracy.
AI8826.GEOID18 height accuracy estimate available here.
AI8826
AI8826.The PID for the CORS L1 Phase Center is AI8827.

AI8826
AI8826.The XYZ, and position/ellipsoidal ht. are equivalent.
AI8826
AI8826.The ellipsoidal height was determined by GPS observations
AI8826.and is referenced to NAD 83.
