DI2208.Formal positional accuracy estimates are not available for this CORS
DI2208.because its coordinates were determined in part using modeled
DI2208.velocities. Approximate one-sigma accuracies for latitude, longitude,
DI2208.and ellipsoid height can be obtained from the short-term time series.
DI2208.Additional information regarding modeled velocities is available on
DI2208.the CORS Coordinates for MYCS2 web page:
DI2208.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DI2208
DI2208.The coordinates were established by GPS observations
DI2208.and adjusted by the National Geodetic Survey in June 2019.
DI2208
DI2208.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI2208.been affixed to the stable North American Tectonic Plate.
DI2208
DI2208.The coordinates are valid at the epoch date displayed above
DI2208.which is a decimal equivalence of Year/Month/Day.
DI2208
DI2208.Due to the release of the International GNSS Service (IGS) 2014
DI2208.realization of the International Terrestrial Reference Frame of 2014
DI2208.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI2208.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI2208.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI2208.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI2208.currently published epoch of 2010.00.

DI2208.Significant digits in the geoid height do not necessarily reflect accuracy.

DI2208.The XYZ, and position/ellipsoidal ht. are equivalent.
DI2208
DI2208.The ellipsoidal height was determined by GPS observations
DI2208.and is referenced to NAD 83.
