DH9015.The coordinates were established by GPS observations
DH9015.and adjusted by the National Geodetic Survey in June 2019.
DH9015
DH9015.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH9015.been affixed to the stable North American Tectonic Plate.
DH9015
DH9015.The coordinates are valid at the epoch date displayed above
DH9015.which is a decimal equivalence of Year/Month/Day.
DH9015
DH9015.Due to the release of the International GNSS Service (IGS) 2014
DH9015.realization of the International Terrestrial Reference Frame of 2014
DH9015.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH9015.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH9015.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH9015.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH9015.currently published epoch of 2010.00.
DH9015
DH9015.Additional information on MYCS2 is available at
DH9015.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH9015
DH9015.The orthometric height was determined by differential leveling and
DH9015.adjusted by the NATIONAL GEODETIC SURVEY
DH9015.in August 2020.
DH9015
DH9015.Significant digits in the geoid height do not necessarily reflect accuracy.
DH9015.GEOID18 height accuracy estimate available here.

DH9015.The PID for the CORS L1 Phase Center is DQ5207.

DH9015.Click photographs - Photos may exist for this station.
DH9015
DH9015.The XYZ, and position/ellipsoidal ht. are equivalent.
DH9015
DH9015.The ellipsoidal height was determined by GPS observations
DH9015.and is referenced to NAD 83.
