DH7158.Formal positional accuracy estimates are not available for this CORS
DH7158.because its coordinates were determined in part using modeled
DH7158.velocities. Approximate one-sigma accuracies for latitude, longitude,
DH7158.and ellipsoid height can be obtained from the short-term time series.
DH7158.Additional information regarding modeled velocities is available on
DH7158.the CORS Coordinates for MYCS2 web page:
DH7158.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DH7158
DH7158.The coordinates were established by GPS observations
DH7158.and adjusted by the National Geodetic Survey in June 2019.
DH7158
DH7158.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH7158.been affixed to the stable North American Tectonic Plate.
DH7158
DH7158.The coordinates are valid at the epoch date displayed above
DH7158.which is a decimal equivalence of Year/Month/Day.
DH7158
DH7158.Due to the release of the International GNSS Service (IGS) 2014
DH7158.realization of the International Terrestrial Reference Frame of 2014
DH7158.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH7158.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH7158.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH7158.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH7158.currently published epoch of 2010.00.

DH7158.The XYZ, and position/ellipsoidal ht. are equivalent.
DH7158
DH7158.The ellipsoidal height was determined by GPS observations
DH7158.and is referenced to NAD 83.
