DQ7574.Formal positional accuracy estimates are not available for this CORS
DQ7574.because its coordinates were determined in part using modeled
DQ7574.velocities. Approximate one-sigma accuracies for latitude, longitude,
DQ7574.and ellipsoid height can be obtained from the short-term time series.
DQ7574.Additional information regarding modeled velocities is available on
DQ7574.the CORS Coordinates for MYCS2 web page:
DQ7574.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DQ7574
DQ7574.The coordinates were established by GPS observations
DQ7574.and adjusted by the National Geodetic Survey in August 2019.
DQ7574
DQ7574.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DQ7574.been affixed to the stable North American Tectonic Plate.
DQ7574
DQ7574.The coordinates are valid at the epoch date displayed above
DQ7574.which is a decimal equivalence of Year/Month/Day.
DQ7574
DQ7574.Due to the release of the International GNSS Service (IGS) 2014
DQ7574.realization of the International Terrestrial Reference Frame of 2014
DQ7574.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DQ7574.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DQ7574.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DQ7574.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DQ7574.currently published epoch of 2010.00.

DQ7574.The XYZ, and position/ellipsoidal ht. are equivalent.
DQ7574
DQ7574.The ellipsoidal height was determined by GPS observations
DQ7574.and is referenced to NAD 83.
