DF3604.Formal positional accuracy estimates are not available for this CORS
DF3604.because its coordinates were determined in part using modeled
DF3604.velocities. Approximate one-sigma accuracies for latitude, longitude,
DF3604.and ellipsoid height can be obtained from the short-term time series.
DF3604.Additional information regarding modeled velocities is available on
DF3604.the CORS Coordinates for MYCS2 web page:
DF3604.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DF3604
DF3604.The coordinates were established by GPS observations
DF3604.and adjusted by the National Geodetic Survey in June 2019.
DF3604
DF3604.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF3604.been affixed to the stable North American Tectonic Plate.
DF3604
DF3604.The coordinates are valid at the epoch date displayed above
DF3604.which is a decimal equivalence of Year/Month/Day.
DF3604
DF3604.Due to the release of the International GNSS Service (IGS) 2014
DF3604.realization of the International Terrestrial Reference Frame of 2014
DF3604.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF3604.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF3604.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF3604.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF3604.currently published epoch of 2010.00.

DF3604.The XYZ, and position/ellipsoidal ht. are equivalent.
DF3604
DF3604.The ellipsoidal height was determined by GPS observations
DF3604.and is referenced to NAD 83.
