DH7227.Formal positional accuracy estimates are not available for this CORS
DH7227.because its coordinates were determined in part using modeled
DH7227.velocities. Approximate one-sigma accuracies for latitude, longitude,
DH7227.and ellipsoid height can be obtained from the short-term time series.
DH7227.Additional information regarding modeled velocities is available on
DH7227.the CORS Coordinates for MYCS2 web page:
DH7227.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DH7227
DH7227.The coordinates were established by GPS observations
DH7227.and adjusted by the National Geodetic Survey in June 2019.
DH7227
DH7227.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH7227.been affixed to the stable North American Tectonic Plate.
DH7227
DH7227.The coordinates are valid at the epoch date displayed above
DH7227.which is a decimal equivalence of Year/Month/Day.
DH7227
DH7227.Due to the release of the International GNSS Service (IGS) 2014
DH7227.realization of the International Terrestrial Reference Frame of 2014
DH7227.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH7227.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH7227.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH7227.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH7227.currently published epoch of 2010.00.

DH7227.The XYZ, and position/ellipsoidal ht. are equivalent.
DH7227
DH7227.The ellipsoidal height was determined by GPS observations
DH7227.and is referenced to NAD 83.
