DL8639.The coordinates were established by GPS observations
DL8639.and adjusted by the National Geodetic Survey in June 2019.
DL8639
DL8639.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL8639.been affixed to the stable North American Tectonic Plate.
DL8639
DL8639.The coordinates are valid at the epoch date displayed above
DL8639.which is a decimal equivalence of Year/Month/Day.
DL8639
DL8639.Due to the release of the International GNSS Service (IGS) 2014
DL8639.realization of the International Terrestrial Reference Frame of 2014
DL8639.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL8639.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL8639.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL8639.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL8639.currently published epoch of 2010.00.
DL8639
DL8639.Additional information on MYCS2 is available at

DL8639.** This station is in an area of known vertical motion. If an
DL8639.** orthometric height was ever established but is not available
DL8639.** in the current survey control section, the orthometric height
DL8639.** is considered suspect. Suspect heights are available in the
DL8639.** superseded section only if requested.
DL8639
DL8639.Significant digits in the geoid height do not necessarily reflect accuracy.
DL8639.GEOID18 height accuracy estimate available here.

DL8639.The PID for the CORS L1 Phase Center is DR1522.

DL8639.Click photographs - Photos may exist for this station.
DL8639
DL8639.The XYZ, and position/ellipsoidal ht. are equivalent.
DL8639
DL8639.The ellipsoidal height was determined by GPS observations
DL8639.and is referenced to NAD 83.
