DF4381.Formal positional accuracy estimates are not available for this CORS
DF4381.because its coordinates were determined in part using modeled
DF4381.velocities. Approximate one-sigma accuracies for latitude, longitude,
DF4381.and ellipsoid height can be obtained from the short-term time series.
DF4381.Additional information regarding modeled velocities is available on
DF4381.the CORS Coordinates for MYCS2 web page:
DF4381.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DF4381
DF4381.The coordinates were established by GPS observations
DF4381.and adjusted by the National Geodetic Survey in March 2023.
DF4381
DF4381.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF4381.been affixed to the stable North American Tectonic Plate.
DF4381
DF4381.The coordinates are valid at the epoch date displayed above
DF4381.which is a decimal equivalence of Year/Month/Day.
DF4381
DF4381.Due to the release of the International GNSS Service (IGS) 2014
DF4381.realization of the International Terrestrial Reference Frame of 2014
DF4381.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF4381.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF4381.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF4381.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF4381.currently published epoch of 2010.00.

DF4381.The XYZ, and position/ellipsoidal ht. are equivalent.
DF4381
DF4381.The ellipsoidal height was determined by GPS observations
DF4381.and is referenced to NAD 83.
