DR7485.Formal positional accuracy estimates are not available for this CORS
DR7485.because its coordinates were determined in part using modeled
DR7485.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR7485.and ellipsoid height can be obtained from the short-term time series.
DR7485.Additional information regarding modeled velocities is available on
DR7485.the CORS Coordinates for MYCS2 web page:
DR7485.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR7485
DR7485.The coordinates were established by GPS observations
DR7485.and adjusted by the National Geodetic Survey in December 2021.
DR7485
DR7485.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DR7485.been affixed to the stable North American Tectonic Plate.
DR7485
DR7485.The coordinates are valid at the epoch date displayed above
DR7485.which is a decimal equivalence of Year/Month/Day.
DR7485
DR7485.Due to the release of the International GNSS Service (IGS) 2014
DR7485.realization of the International Terrestrial Reference Frame of 2014
DR7485.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR7485.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR7485.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR7485.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR7485.currently published epoch of 2010.00.
