DR8630.Formal positional accuracy estimates are not available for this CORS
DR8630.because its coordinates were determined in part using modeled
DR8630.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR8630.and ellipsoid height can be obtained from the short-term time series.
DR8630.Additional information regarding modeled velocities is available on
DR8630.the CORS Coordinates for MYCS2 web page:
DR8630.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR8630
DR8630.The coordinates were established by GPS observations
DR8630.and adjusted by the National Geodetic Survey in February 2023.
DR8630
DR8630.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DR8630.been affixed to the stable North American Tectonic Plate.
DR8630
DR8630.The coordinates are valid at the epoch date displayed above
DR8630.which is a decimal equivalence of Year/Month/Day.
DR8630
DR8630.Due to the release of the International GNSS Service (IGS) 2014
DR8630.realization of the International Terrestrial Reference Frame of 2014
DR8630.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR8630.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR8630.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR8630.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR8630.currently published epoch of 2010.00.

DR8630.The XYZ, and position/ellipsoidal ht. are equivalent.
DR8630
DR8630.The ellipsoidal height was determined by GPS observations
DR8630.and is referenced to NAD 83.
