DP8346.Formal positional accuracy estimates are not available for this CORS
DP8346.because its coordinates were determined in part using modeled
DP8346.velocities. Approximate one-sigma accuracies for latitude, longitude,
DP8346.and ellipsoid height can be obtained from the short-term time series.
DP8346.Additional information regarding modeled velocities is available on
DP8346.the CORS Coordinates for MYCS2 web page:
DP8346.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DP8346
DP8346.The coordinates were established by GPS observations
DP8346.and adjusted by the National Geodetic Survey in June 2019.
DP8346
DP8346.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP8346.been affixed to the stable North American Tectonic Plate.
DP8346
DP8346.The coordinates are valid at the epoch date displayed above
DP8346.which is a decimal equivalence of Year/Month/Day.
DP8346
DP8346.Due to the release of the International GNSS Service (IGS) 2014
DP8346.realization of the International Terrestrial Reference Frame of 2014
DP8346.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP8346.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP8346.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP8346.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP8346.currently published epoch of 2010.00.

DP8346.The XYZ, and position/ellipsoidal ht. are equivalent.
DP8346
DP8346.The ellipsoidal height was determined by GPS observations
DP8346.and is referenced to NAD 83.
