DH4178.Formal positional accuracy estimates are not available for this CORS
DH4178.because its coordinates were determined in part using modeled
DH4178.velocities. Approximate one-sigma accuracies for latitude, longitude,
DH4178.and ellipsoid height can be obtained from the short-term time series.
DH4178.Additional information regarding modeled velocities is available on
DH4178.the CORS Coordinates for MYCS2 web page:
DH4178.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DH4178
DH4178.The coordinates were established by GPS observations
DH4178.and adjusted by the National Geodetic Survey in June 2005.
DH4178
DH4178.The datum tag of NAD 83(CORS) is equivalent to NAD 83(CORS96).
DH4178
DH4178.The coordinates are valid at the epoch date displayed above
DH4178.which is a decimal equivalence of Year/Month/Day.
DH4178
DH4178.Due to the release of the International GNSS Service (IGS) 2014
DH4178.realization of the International Terrestrial Reference Frame of 2014
DH4178.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH4178.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH4178.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH4178.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH4178.currently published epoch of 2010.00.

DH4178.The XYZ, and position/ellipsoidal ht. are equivalent.
DH4178
DH4178.The ellipsoidal height was determined by GPS observations
DH4178.and is referenced to NAD 83.
