DE8091.The coordinates were established by GPS observations
DE8091.and adjusted by the National Geodetic Survey in June 2019.
DE8091
DE8091.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DE8091.been affixed to the stable North American Tectonic Plate.
DE8091
DE8091.The coordinates are valid at the epoch date displayed above
DE8091.which is a decimal equivalence of Year/Month/Day.
DE8091
DE8091.Due to the release of the International GNSS Service (IGS) 2014
DE8091.realization of the International Terrestrial Reference Frame of 2014
DE8091.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DE8091.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DE8091.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DE8091.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DE8091.currently published epoch of 2010.00.
DE8091
DE8091.Additional information on MYCS2 is available at

DE8091.** This station is in an area of known vertical motion. If an
DE8091.** orthometric height was ever established but is not available
DE8091.** in the current survey control section, the orthometric height
DE8091.** is considered suspect. Suspect heights are available in the
DE8091.** superseded section only if requested.
DE8091
DE8091.Significant digits in the geoid height do not necessarily reflect accuracy.

DE8091.The XYZ, and position/ellipsoidal ht. are equivalent.
DE8091
DE8091.The ellipsoidal height was determined by GPS observations
DE8091.and is referenced to NAD 83.
