DQ7572.Formal positional accuracy estimates are not available for this CORS
DQ7572.because its coordinates were determined in part using modeled
DQ7572.velocities. Approximate one-sigma accuracies for latitude, longitude,
DQ7572.and ellipsoid height can be obtained from the short-term time series.
DQ7572.Additional information regarding modeled velocities is available on
DQ7572.the CORS Coordinates for MYCS2 web page:
DQ7572.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DQ7572
DQ7572.The coordinates were established by GPS observations
DQ7572.and adjusted by the National Geodetic Survey in August 2019.
DQ7572
DQ7572.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DQ7572.been affixed to the stable North American Tectonic Plate.
DQ7572
DQ7572.The coordinates are valid at the epoch date displayed above
DQ7572.which is a decimal equivalence of Year/Month/Day.
DQ7572
DQ7572.Due to the release of the International GNSS Service (IGS) 2014
DQ7572.realization of the International Terrestrial Reference Frame of 2014
DQ7572.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DQ7572.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DQ7572.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DQ7572.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DQ7572.currently published epoch of 2010.00.

DQ7572.The XYZ, and position/ellipsoidal ht. are equivalent.
DQ7572
DQ7572.The ellipsoidal height was determined by GPS observations
DQ7572.and is referenced to NAD 83.
