DJ7874.Formal positional accuracy estimates are not available for this CORS
DJ7874.because its coordinates were determined in part using modeled
DJ7874.velocities. Approximate one-sigma accuracies for latitude, longitude,
DJ7874.and ellipsoid height can be obtained from the short-term time series.
DJ7874.Additional information regarding modeled velocities is available on
DJ7874.the CORS Coordinates for MYCS2 web page:
DJ7874.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DJ7874
DJ7874.The coordinates were established by GPS observations
DJ7874.and adjusted by the National Geodetic Survey in March 2024.

DJ7874.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DJ7874.been affixed to the stable North American Tectonic Plate.
DJ7874
DJ7874.The coordinates are valid at the epoch date displayed above
DJ7874.which is a decimal equivalence of Year/Month/Day.
DJ7874
DJ7874.Due to the release of the International GNSS Service (IGS) 2014
DJ7874.realization of the International Terrestrial Reference Frame of 2014
DJ7874.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DJ7874.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DJ7874.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DJ7874.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DJ7874.currently published epoch of 2010.00.

DJ7874.The XYZ, and position/ellipsoidal ht. are equivalent.
DJ7874
DJ7874.The ellipsoidal height was determined by GPS observations
DJ7874.and is referenced to NAD 83.
