DH9596.The coordinates were established by GPS observations
DH9596.and adjusted by the National Geodetic Survey in June 2019.
DH9596
DH9596.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH9596.been affixed to the stable North American Tectonic Plate.
DH9596
DH9596.The coordinates are valid at the epoch date displayed above
DH9596.which is a decimal equivalence of Year/Month/Day.
DH9596
DH9596.Due to the release of the International GNSS Service (IGS) 2014
DH9596.realization of the International Terrestrial Reference Frame of 2014
DH9596.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH9596.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH9596.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH9596.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH9596.currently published epoch of 2010.00.
DH9596
DH9596.Additional information on MYCS2 is available at

DH9596.** This station is in an area of known vertical motion. If an
DH9596.** orthometric height was ever established but is not available
DH9596.** in the current survey control section, the orthometric height
DH9596.** is considered suspect. Suspect heights are available in the
DH9596.** superseded section only if requested.
DH9596
DH9596.Significant digits in the geoid height do not necessarily reflect accuracy.
DH9596.GEOID18 height accuracy estimate available here.

DH9596.The PID for the CORS L1 Phase Center is DR1496.

DH9596
DH9596.The XYZ, and position/ellipsoidal ht. are equivalent.
DH9596
DH9596.The ellipsoidal height was determined by GPS observations
DH9596.and is referenced to NAD 83.
