DM7831.The coordinates were established by GPS observations
DM7831.and adjusted by the National Geodetic Survey in June 2022.
DM7831
DM7831.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7831.been affixed to the stable North American Tectonic Plate.
DM7831
DM7831.The coordinates are valid at the epoch date displayed above
DM7831.which is a decimal equivalence of Year/Month/Day.
DM7831
DM7831.Due to the release of the International GNSS Service (IGS) 2014
DM7831.realization of the International Terrestrial Reference Frame of 2014
DM7831.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7831.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7831.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7831.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7831.currently published epoch of 2010.00.
DM7831
DM7831.Additional information on MYCS2 is available at
DM7831.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM7831
DM7831.The orthometric height was determined by GPS observations and a
DM7831.high-resolution geoid model.
DM7831
DM7831.Significant digits in the geoid height do not necessarily reflect accuracy.
DM7831.GEOID18 height accuracy estimate available here.

DM7831.The PID for the CORS L1 Phase Center is DR3624.

DM7831
DM7831.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7831
DM7831.The ellipsoidal height was determined by GPS observations
DM7831.and is referenced to NAD 83.
