DR3051.Formal positional accuracy estimates are not available for this CORS
DR3051.because its coordinates were determined in part using modeled
DR3051.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR3051.and ellipsoid height can be obtained from the short-term time series.
DR3051.Additional information regarding modeled velocities is available on
DR3051.the CORS Coordinates for MYCS2 web page:
DR3051.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR3051
DR3051.The coordinates were established by GPS observations
DR3051.and adjusted by the National Geodetic Survey in September 2019.
DR3051
DR3051.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DR3051.been affixed to the stable North American Tectonic Plate.
DR3051
DR3051.The coordinates are valid at the epoch date displayed above
DR3051.which is a decimal equivalence of Year/Month/Day.
DR3051
DR3051.Due to the release of the International GNSS Service (IGS) 2014
DR3051.realization of the International Terrestrial Reference Frame of 2014
DR3051.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR3051.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR3051.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR3051.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR3051.currently published epoch of 2010.00.

DR3051.The XYZ, and position/ellipsoidal ht. are equivalent.
DR3051
DR3051.The ellipsoidal height was determined by GPS observations
DR3051.and is referenced to NAD 83.
