DG5338.Formal positional accuracy estimates are not available for this CORS
DG5338.because its coordinates were determined in part using modeled
DG5338.velocities. Approximate one-sigma accuracies for latitude, longitude,
DG5338.and ellipsoid height can be obtained from the short-term time series.
DG5338.Additional information regarding modeled velocities is available on
DG5338.the CORS Coordinates for MYCS2 web page:
DG5338.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DG5338
DG5338.The coordinates were established by GPS observations
DG5338.and adjusted by the National Geodetic Survey in July 2005.
DG5338
DG5338.The datum tag of NAD 83(CORS) is equivalent to NAD 83(CORS96).
DG5338
DG5338.The coordinates are valid at the epoch date displayed above
DG5338.which is a decimal equivalence of Year/Month/Day.
DG5338
DG5338.Due to the release of the International GNSS Service (IGS) 2014
DG5338.realization of the International Terrestrial Reference Frame of 2014
DG5338.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG5338.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG5338.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG5338.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG5338.currently published epoch of 2010.00.

DG5338.Significant digits in the geoid height do not necessarily reflect accuracy.

DG5338.The XYZ, and position/ellipsoidal ht. are equivalent.
DG5338
DG5338.The ellipsoidal height was determined by GPS observations
DG5338.and is referenced to NAD 83.
