DQ7021.Formal positional accuracy estimates are not available for this CORS
DQ7021.because its coordinates were determined in part using modeled
DQ7021.velocities. Approximate one-sigma accuracies for latitude, longitude,
DQ7021.and ellipsoid height can be obtained from the short-term time series.
DQ7021.Additional information regarding modeled velocities is available on
DQ7021.the CORS Coordinates for MYCS2 web page:
DQ7021.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DQ7021
DQ7021.The coordinates were established by GPS observations
DQ7021.and adjusted by the National Geodetic Survey in August 2019.
DQ7021
DQ7021.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DQ7021.been affixed to the stable North American Tectonic Plate.
DQ7021
DQ7021.The coordinates are valid at the epoch date displayed above
DQ7021.which is a decimal equivalence of Year/Month/Day.
DQ7021
DQ7021.Due to the release of the International GNSS Service (IGS) 2014
DQ7021.realization of the International Terrestrial Reference Frame of 2014
DQ7021.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DQ7021.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DQ7021.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DQ7021.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DQ7021.currently published epoch of 2010.00.

DQ7021.The XYZ, and position/ellipsoidal ht. are equivalent.
DQ7021
DQ7021.The ellipsoidal height was determined by GPS observations
DQ7021.and is referenced to NAD 83.
