DK3338.The coordinates were established by GPS observations
DK3338.and adjusted by the National Geodetic Survey in June 2019.
DK3338
DK3338.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK3338.been affixed to the stable North American Tectonic Plate.
DK3338
DK3338.The coordinates are valid at the epoch date displayed above
DK3338.which is a decimal equivalence of Year/Month/Day.
DK3338
DK3338.Due to the release of the International GNSS Service (IGS) 2014
DK3338.realization of the International Terrestrial Reference Frame of 2014
DK3338.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK3338.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK3338.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK3338.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK3338.currently published epoch of 2010.00.
DK3338
DK3338.Additional information on MYCS2 is available at
DK3338.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DK3338.** This station is in an area of known vertical motion. Due to the
DK3338.** variability of land subsidence, uplift, and crustal motion, NGS has,
DK3338.** determined the orthometric heights for marks in these suspect
DK3338.** subsidence areas should be considered valid only at the epoch date
DK3338.** associated with the orthometric height. These heights must always
DK3338.** be validated when used as control. All previously superseded
DK3338.** orthometric heights are now considered suspect and are available
DK3338.** in the superseded section. NGS does not recommend using suspect
DK3338.** or superseded heights as control.
DK3338
DK3338.The orthometric height was determined by GPS observations and a
DK3338.high-resolution geoid model using precise GPS observation and
DK3338.processing techniques.
DK3338
DK3338.Significant digits in the geoid height do not necessarily reflect accuracy.
DK3338.GEOID18 height accuracy estimate available here.
DK3338
DK3338.The PID for the CORS L1 Phase Center is DL3084.

DK3338
DK3338.The XYZ, and position/ellipsoidal ht. are equivalent.
DK3338
DK3338.The ellipsoidal height was determined by GPS observations
DK3338.and is referenced to NAD 83.
