DG9105.Formal positional accuracy estimates are not available for this CORS
DG9105.because its coordinates were determined in part using modeled
DG9105.velocities. Approximate one-sigma accuracies for latitude, longitude,
DG9105.and ellipsoid height can be obtained from the short-term time series.
DG9105.Additional information regarding modeled velocities is available on
DG9105.the CORS Coordinates for MYCS2 web page:
DG9105.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DG9105
DG9105.The coordinates were established by GPS observations
DG9105.and adjusted by the National Geodetic Survey in June 2019.
DG9105
DG9105.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9105.been affixed to the stable North American Tectonic Plate.
DG9105
DG9105.The coordinates are valid at the epoch date displayed above
DG9105.which is a decimal equivalence of Year/Month/Day.
DG9105
DG9105.Due to the release of the International GNSS Service (IGS) 2014
DG9105.realization of the International Terrestrial Reference Frame of 2014
DG9105.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9105.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9105.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9105.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9105.currently published epoch of 2010.00.

DG9105.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9105
DG9105.The ellipsoidal height was determined by GPS observations
DG9105.and is referenced to NAD 83.
