DL7767.The coordinates were established by GPS observations
DL7767.and adjusted by the National Geodetic Survey in June 2019.
DL7767
DL7767.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7767.been affixed to the stable North American Tectonic Plate.
DL7767
DL7767.The coordinates are valid at the epoch date displayed above
DL7767.which is a decimal equivalence of Year/Month/Day.
DL7767
DL7767.Due to the release of the International GNSS Service (IGS) 2014
DL7767.realization of the International Terrestrial Reference Frame of 2014
DL7767.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7767.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7767.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7767.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7767.currently published epoch of 2010.00.
DL7767
DL7767.Additional information on MYCS2 is available at
DL7767.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL7767
DL7767.The orthometric height was determined by differential leveling and
DL7767.adjusted by the NATIONAL GEODETIC SURVEY
DL7767.in September 2024.
DL7767
DL7767.Significant digits in the geoid height do not necessarily reflect accuracy.
DL7767.GEOID18 height accuracy estimate available here.

DL7767.The PID for the CORS L1 Phase Center is DR7694.

DL7767
DL7767.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7767
DL7767.The ellipsoidal height was determined by GPS observations
DL7767.and is referenced to NAD 83.
