DR3057.Formal positional accuracy estimates are not available for this CORS
DR3057.because its coordinates were determined in part using modeled
DR3057.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR3057.and ellipsoid height can be obtained from the short-term time series.
DR3057.Additional information regarding modeled velocities is available on
DR3057.the CORS Coordinates for MYCS2 web page:
DR3057.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR3057
DR3057.The coordinates were established by GPS observations
DR3057.and adjusted by the National Geodetic Survey in September 2019.
DR3057
DR3057.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DR3057.been affixed to the stable North American Tectonic Plate.
DR3057
DR3057.The coordinates are valid at the epoch date displayed above
DR3057.which is a decimal equivalence of Year/Month/Day.
DR3057
DR3057.Due to the release of the International GNSS Service (IGS) 2014
DR3057.realization of the International Terrestrial Reference Frame of 2014
DR3057.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR3057.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR3057.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR3057.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR3057.currently published epoch of 2010.00.

DR3057.The XYZ, and position/ellipsoidal ht. are equivalent.
DR3057
DR3057.The ellipsoidal height was determined by GPS observations
DR3057.and is referenced to NAD 83.
