DP6621.Formal positional accuracy estimates are not available for this CORS
DP6621.because its coordinates were determined in part using modeled
DP6621.velocities. Approximate one-sigma accuracies for latitude, longitude,
DP6621.and ellipsoid height can be obtained from the short-term time series.
DP6621.Additional information regarding modeled velocities is available on
DP6621.the CORS Coordinates for MYCS2 web page:
DP6621.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DP6621
DP6621.The coordinates were established by GPS observations
DP6621.and adjusted by the National Geodetic Survey in June 2019.
DP6621
DP6621.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP6621.been affixed to the stable North American Tectonic Plate.
DP6621
DP6621.The coordinates are valid at the epoch date displayed above
DP6621.which is a decimal equivalence of Year/Month/Day.
DP6621
DP6621.Due to the release of the International GNSS Service (IGS) 2014
DP6621.realization of the International Terrestrial Reference Frame of 2014
DP6621.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP6621.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP6621.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP6621.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP6621.currently published epoch of 2010.00.

DP6621.The XYZ, and position/ellipsoidal ht. are equivalent.
DP6621
DP6621.The ellipsoidal height was determined by GPS observations
DP6621.and is referenced to NAD 83.
