DF5272.The coordinates were established by GPS observations
DF5272.and adjusted by the National Geodetic Survey in June 2019.
DF5272
DF5272.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF5272.been affixed to the stable North American Tectonic Plate.
DF5272
DF5272.The coordinates are valid at the epoch date displayed above
DF5272.which is a decimal equivalence of Year/Month/Day.
DF5272
DF5272.Due to the release of the International GNSS Service (IGS) 2014
DF5272.realization of the International Terrestrial Reference Frame of 2014
DF5272.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF5272.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF5272.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF5272.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF5272.currently published epoch of 2010.00.
DF5272
DF5272.Additional information on MYCS2 is available at
DF5272.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF5272
DF5272.The orthometric height was determined by GPS observations and a
DF5272.high-resolution geoid model using precise GPS observation and
DF5272.processing techniques.
DF5272
DF5272.Significant digits in the geoid height do not necessarily reflect accuracy.
DF5272.GEOID18 height accuracy estimate available here.
DF5272
DF5272.The PID for the CORS L1 Phase Center is DN7589.

DF5272
DF5272.The XYZ, and position/ellipsoidal ht. are equivalent.
DF5272
DF5272.The ellipsoidal height was determined by GPS observations
DF5272.and is referenced to NAD 83.
