DQ5294.Formal positional accuracy estimates are not available for this CORS
DQ5294.because its coordinates were determined in part using modeled
DQ5294.velocities. Approximate one-sigma accuracies for latitude, longitude,
DQ5294.and ellipsoid height can be obtained from the short-term time series.
DQ5294.Additional information regarding modeled velocities is available on
DQ5294.the CORS Coordinates for MYCS2 web page:
DQ5294.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DQ5294
DQ5294.The coordinates were established by GPS observations
DQ5294.and adjusted by the National Geodetic Survey in May 2021.
DQ5294
DQ5294.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DQ5294.been affixed to the stable North American Tectonic Plate.
DQ5294
DQ5294.The coordinates are valid at the epoch date displayed above
DQ5294.which is a decimal equivalence of Year/Month/Day.
DQ5294
DQ5294.Due to the release of the International GNSS Service (IGS) 2014
DQ5294.realization of the International Terrestrial Reference Frame of 2014
DQ5294.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DQ5294.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DQ5294.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DQ5294.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DQ5294.currently published epoch of 2010.00.

DQ5294.The XYZ, and position/ellipsoidal ht. are equivalent.
DQ5294
DQ5294.The ellipsoidal height was determined by GPS observations
DQ5294.and is referenced to NAD 83.
