DS2080.Formal positional accuracy estimates are not available for this CORS
DS2080.because its coordinates were determined in part using modeled
DS2080.velocities. Approximate one-sigma accuracies for latitude, longitude,
DS2080.and ellipsoid height can be obtained from the short-term time series.
DS2080.Additional information regarding modeled velocities is available on
DS2080.the CORS Coordinates for MYCS2 web page:
DS2080.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DS2080
DS2080.The coordinates were established by GPS observations
DS2080.and adjusted by the National Geodetic Survey in July 2024.
DS2080
DS2080.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DS2080.been affixed to the stable North American Tectonic Plate.
DS2080
DS2080.The coordinates are valid at the epoch date displayed above
DS2080.which is a decimal equivalence of Year/Month/Day.
DS2080
DS2080.Due to the release of the International GNSS Service (IGS) 2014
DS2080.realization of the International Terrestrial Reference Frame of 2014
DS2080.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DS2080.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DS2080.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DS2080.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DS2080.currently published epoch of 2010.00.

DS2080.The XYZ, and position/ellipsoidal ht. are equivalent.
DS2080
DS2080.The ellipsoidal height was determined by GPS observations
DS2080.and is referenced to NAD 83.
