DF6305.The coordinates were established by GPS observations
DF6305.and adjusted by the National Geodetic Survey in March 2024.
DF6305
DF6305.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF6305.been affixed to the stable North American Tectonic Plate.
DF6305
DF6305.The coordinates are valid at the epoch date displayed above
DF6305.which is a decimal equivalence of Year/Month/Day.
DF6305
DF6305.Due to the release of the International GNSS Service (IGS) 2014
DF6305.realization of the International Terrestrial Reference Frame of 2014
DF6305.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF6305.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF6305.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF6305.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF6305.currently published epoch of 2010.00.
DF6305
DF6305.Additional information on MYCS2 is available at
DF6305.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF6305
DF6305.The orthometric height was determined by GPS observations and a
DF6305.high-resolution geoid model using precise GPS observation and
DF6305.processing techniques.
DF6305
DF6305.Significant digits in the geoid height do not necessarily reflect accuracy.
DF6305.GEOID18 height accuracy estimate available here.
DF6305
DF6305.The PID for the CORS L1 Phase Center is DS2733.

DF6305
DF6305.The XYZ, and position/ellipsoidal ht. are equivalent.
DF6305
DF6305.The ellipsoidal height was determined by GPS observations
DF6305.and is referenced to NAD 83.
