DG8333.Formal positional accuracy estimates are not available for this CORS
DG8333.because its coordinates were determined in part using modeled
DG8333.velocities. Approximate one-sigma accuracies for latitude, longitude,
DG8333.and ellipsoid height can be obtained from the short-term time series.
DG8333.Additional information regarding modeled velocities is available on
DG8333.the CORS Coordinates for MYCS2 web page:
DG8333.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DG8333
DG8333.The coordinates were established by GPS observations
DG8333.and adjusted by the National Geodetic Survey in June 2019.
DG8333
DG8333.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG8333.been affixed to the stable North American Tectonic Plate.
DG8333
DG8333.The coordinates are valid at the epoch date displayed above
DG8333.which is a decimal equivalence of Year/Month/Day.
DG8333
DG8333.Due to the release of the International GNSS Service (IGS) 2014
DG8333.realization of the International Terrestrial Reference Frame of 2014
DG8333.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG8333.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG8333.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG8333.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG8333.currently published epoch of 2010.00.

DG8333.The XYZ, and position/ellipsoidal ht. are equivalent.
DG8333
DG8333.The ellipsoidal height was determined by GPS observations
DG8333.and is referenced to NAD 83.
