DF8479.Formal positional accuracy estimates are not available for this CORS
DF8479.because its coordinates were determined in part using modeled
DF8479.velocities. Approximate one-sigma accuracies for latitude, longitude,
DF8479.and ellipsoid height can be obtained from the short-term time series.
DF8479.Additional information regarding modeled velocities is available on
DF8479.the CORS Coordinates for MYCS2 web page:
DF8479.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DF8479
DF8479.The coordinates were established by GPS observations
DF8479.and adjusted by the National Geodetic Survey in October 2003.
DF8479
DF8479.The datum tag of NAD 83(CORS) is equivalent to NAD 83(CORS96).
DF8479
DF8479.The coordinates are valid at the epoch date displayed above
DF8479.which is a decimal equivalence of Year/Month/Day.
DF8479
DF8479.Due to the release of the International GNSS Service (IGS) 2014
DF8479.realization of the International Terrestrial Reference Frame of 2014
DF8479.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8479.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8479.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8479.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8479.currently published epoch of 2010.00.

DF8479.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8479
DF8479.The ellipsoidal height was determined by GPS observations
DF8479.and is referenced to NAD 83.
