DK3342.Formal positional accuracy estimates are not available for this CORS
DK3342.because its coordinates were determined in part using modeled
DK3342.velocities. Approximate one-sigma accuracies for latitude, longitude,
DK3342.and ellipsoid height can be obtained from the short-term time series.
DK3342.Additional information regarding modeled velocities is available on
DK3342.the CORS Coordinates for MYCS2 web page:
DK3342.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DK3342
DK3342.The coordinates were established by GPS observations
DK3342.and adjusted by the National Geodetic Survey in June 2019.
DK3342
DK3342.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK3342.been affixed to the stable North American Tectonic Plate.
DK3342
DK3342.The coordinates are valid at the epoch date displayed above
DK3342.which is a decimal equivalence of Year/Month/Day.
DK3342
DK3342.Due to the release of the International GNSS Service (IGS) 2014
DK3342.realization of the International Terrestrial Reference Frame of 2014
DK3342.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK3342.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK3342.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK3342.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK3342.currently published epoch of 2010.00.

DK3342.** This station is in an area of known vertical motion. Due to the
DK3342.** variability of land subsidence, uplift, and crustal motion, NGS has,
DK3342.** determined the orthometric heights for marks in these suspect
DK3342.** subsidence areas should be considered valid only at the epoch date
DK3342.** associated with the orthometric height. These heights must always
DK3342.** be validated when used as control. All previously superseded
DK3342.** orthometric heights are now considered suspect and are available
DK3342.** in the superseded section. NGS does not recommend using suspect
DK3342.** or superseded heights as control.
DK3342
DK3342.The orthometric height was determined by GPS observations and a
DK3342.high-resolution geoid model using precise GPS observation and
DK3342.processing techniques.
DK3342
DK3342.Significant digits in the geoid height do not necessarily reflect accuracy.
DK3342.GEOID18 height accuracy estimate available here.

DK3342.The PID for the CORS L1 Phase Center is DK3343.

DK3342.The XYZ, and position/ellipsoidal ht. are equivalent.
DK3342
DK3342.The ellipsoidal height was determined by GPS observations
DK3342.and is referenced to NAD 83.
