DQ6620.Formal positional accuracy estimates are not available for this CORS
DQ6620.because its coordinates were determined in part using modeled
DQ6620.velocities. Approximate one-sigma accuracies for latitude, longitude,
DQ6620.and ellipsoid height can be obtained from the short-term time series.
DQ6620.Additional information regarding modeled velocities is available on
DQ6620.the CORS Coordinates for MYCS2 web page:
DQ6620.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DQ6620
DQ6620.The coordinates were established by GPS observations
DQ6620.and adjusted by the National Geodetic Survey in March 2024.
DQ6620
DQ6620.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DQ6620.been affixed to the stable North American Tectonic Plate.
DQ6620
DQ6620.The coordinates are valid at the epoch date displayed above
DQ6620.which is a decimal equivalence of Year/Month/Day.
DQ6620
DQ6620.Due to the release of the International GNSS Service (IGS) 2014
DQ6620.realization of the International Terrestrial Reference Frame of 2014
DQ6620.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DQ6620.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DQ6620.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DQ6620.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DQ6620.currently published epoch of 2010.00.

DQ6620.Significant digits in the geoid height do not necessarily reflect accuracy.
DQ6620.GEOID12B height accuracy estimate available here.

DQ6620.The XYZ, and position/ellipsoidal ht. are equivalent.
DQ6620
DQ6620.The ellipsoidal height was determined by GPS observations
DQ6620.and is referenced to NAD 83.
