DR8622.Formal positional accuracy estimates are not available for this CORS
DR8622.because its coordinates were determined in part using modeled
DR8622.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR8622.and ellipsoid height can be obtained from the short-term time series.
DR8622.Additional information regarding modeled velocities is available on
DR8622.the CORS Coordinates for MYCS2 web page:
DR8622.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR8622
DR8622.The coordinates were established by GPS observations
DR8622.and adjusted by the National Geodetic Survey in February 2023.
DR8622
DR8622.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DR8622.been affixed to the stable North American Tectonic Plate.
DR8622
DR8622.The coordinates are valid at the epoch date displayed above
DR8622.which is a decimal equivalence of Year/Month/Day.
DR8622
DR8622.Due to the release of the International GNSS Service (IGS) 2014
DR8622.realization of the International Terrestrial Reference Frame of 2014
DR8622.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR8622.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR8622.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR8622.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR8622.currently published epoch of 2010.00.

DR8622.The XYZ, and position/ellipsoidal ht. are equivalent.
DR8622
DR8622.The ellipsoidal height was determined by GPS observations
DR8622.and is referenced to NAD 83.
