DL3999.Formal positional accuracy estimates are not available for this CORS
DL3999.because its coordinates were determined in part using modeled
DL3999.velocities. Approximate one-sigma accuracies for latitude, longitude,
DL3999.and ellipsoid height can be obtained from the short-term time series.
DL3999.Additional information regarding modeled velocities is available on
DL3999.the CORS Coordinates for MYCS2 web page:
DL3999.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DL3999
DL3999.The coordinates were established by GPS observations
DL3999.and adjusted by the National Geodetic Survey in June 2019.
DL3999
DL3999.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3999.been affixed to the stable North American Tectonic Plate.
DL3999
DL3999.The coordinates are valid at the epoch date displayed above
DL3999.which is a decimal equivalence of Year/Month/Day.
DL3999
DL3999.Due to the release of the International GNSS Service (IGS) 2014
DL3999.realization of the International Terrestrial Reference Frame of 2014
DL3999.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3999.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3999.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3999.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3999.currently published epoch of 2010.00.

DL3999.Significant digits in the geoid height do not necessarily reflect accuracy.

DL3999.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3999
DL3999.The ellipsoidal height was determined by GPS observations
DL3999.and is referenced to NAD 83.
