DH7221.The coordinates were established by GPS observations
DH7221.and adjusted by the National Geodetic Survey in June 2019.
DH7221
DH7221.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH7221.been affixed to the stable North American Tectonic Plate.
DH7221
DH7221.The coordinates are valid at the epoch date displayed above
DH7221.which is a decimal equivalence of Year/Month/Day.
DH7221
DH7221.Due to the release of the International GNSS Service (IGS) 2014
DH7221.realization of the International Terrestrial Reference Frame of 2014
DH7221.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH7221.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH7221.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH7221.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH7221.currently published epoch of 2010.00.
DH7221
DH7221.Additional information on MYCS2 is available at
DH7221.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH7221
DH7221.The orthometric height was determined by differential leveling and
DH7221.adjusted by the NATIONAL GEODETIC SURVEY
DH7221.in October 2009.
DH7221
DH7221.No vertical observational check was made to the station.
DH7221
DH7221.Significant digits in the geoid height do not necessarily reflect accuracy.
DH7221.GEOID18 height accuracy estimate available here.
DH7221
DH7221.The PID for the CORS L1 Phase Center is DR6167.

DH7221.The XYZ, and position/ellipsoidal ht. are equivalent.
DH7221
DH7221.The ellipsoidal height was determined by GPS observations
DH7221.and is referenced to NAD 83.
