DR8471.Formal positional accuracy estimates are not available for this CORS
DR8471.because its coordinates were determined in part using modeled
DR8471.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR8471.and ellipsoid height can be obtained from the short-term time series.
DR8471.Additional information regarding modeled velocities is available on
DR8471.the CORS Coordinates for MYCS2 web page:
DR8471.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR8471
DR8471.The coordinates were established by GPS observations
DR8471.and adjusted by the National Geodetic Survey in October 2022.
DR8471
DR8471.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DR8471.been affixed to the stable North American Tectonic Plate.
DR8471
DR8471.The coordinates are valid at the epoch date displayed above
DR8471.which is a decimal equivalence of Year/Month/Day.
DR8471
DR8471.Due to the release of the International GNSS Service (IGS) 2014
DR8471.realization of the International Terrestrial Reference Frame of 2014
DR8471.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR8471.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR8471.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR8471.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR8471.currently published epoch of 2010.00.

DR8471.The XYZ, and position/ellipsoidal ht. are equivalent.
DR8471
DR8471.The ellipsoidal height was determined by GPS observations
DR8471.and is referenced to NAD 83.
