DG5484.Formal positional accuracy estimates are not available for this CORS
DG5484.because its coordinates were determined in part using modeled
DG5484.velocities. Approximate one-sigma accuracies for latitude, longitude,
DG5484.and ellipsoid height can be obtained from the short-term time series.
DG5484.Additional information regarding modeled velocities is available on
DG5484.the CORS Coordinates for MYCS2 web page:
DG5484.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DG5484
DG5484.The coordinates were established by GPS observations
DG5484.and adjusted by the National Geodetic Survey in June 2019.
DG5484
DG5484.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG5484.been affixed to the stable North American Tectonic Plate.
DG5484
DG5484.The coordinates are valid at the epoch date displayed above
DG5484.which is a decimal equivalence of Year/Month/Day.
DG5484
DG5484.Due to the release of the International GNSS Service (IGS) 2014
DG5484.realization of the International Terrestrial Reference Frame of 2014
DG5484.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG5484.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG5484.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG5484.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG5484.currently published epoch of 2010.00.

DG5484.The XYZ, and position/ellipsoidal ht. are equivalent.
DG5484
DG5484.The ellipsoidal height was determined by GPS observations
DG5484.and is referenced to NAD 83.
