DH7225.Formal positional accuracy estimates are not available for this CORS
DH7225.because its coordinates were determined in part using modeled
DH7225.velocities. Approximate one-sigma accuracies for latitude, longitude,
DH7225.and ellipsoid height can be obtained from the short-term time series.
DH7225.Additional information regarding modeled velocities is available on
DH7225.the CORS Coordinates for MYCS2 web page:
DH7225.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DH7225
DH7225.The coordinates were established by GPS observations
DH7225.and adjusted by the National Geodetic Survey in June 2019.
DH7225
DH7225.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH7225.been affixed to the stable North American Tectonic Plate.
DH7225
DH7225.The coordinates are valid at the epoch date displayed above
DH7225.which is a decimal equivalence of Year/Month/Day.
DH7225
DH7225.Due to the release of the International GNSS Service (IGS) 2014
DH7225.realization of the International Terrestrial Reference Frame of 2014
DH7225.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH7225.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH7225.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH7225.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH7225.currently published epoch of 2010.00.

DH7225.The XYZ, and position/ellipsoidal ht. are equivalent.
DH7225
DH7225.The ellipsoidal height was determined by GPS observations
DH7225.and is referenced to NAD 83.
