DG9298.Formal positional accuracy estimates are not available for this CORS
DG9298.because its coordinates were determined in part using modeled
DG9298.velocities. Approximate one-sigma accuracies for latitude, longitude,
DG9298.and ellipsoid height can be obtained from the short-term time series.
DG9298.Additional information regarding modeled velocities is available on
DG9298.the CORS Coordinates for MYCS2 web page:
DG9298.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DG9298
DG9298.The coordinates were established by GPS observations
DG9298.and adjusted by the National Geodetic Survey in June 2019.
DG9298
DG9298.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9298.been affixed to the stable North American Tectonic Plate.
DG9298
DG9298.The coordinates are valid at the epoch date displayed above
DG9298.which is a decimal equivalence of Year/Month/Day.
DG9298
DG9298.Due to the release of the International GNSS Service (IGS) 2014
DG9298.realization of the International Terrestrial Reference Frame of 2014
DG9298.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9298.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9298.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9298.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9298.currently published epoch of 2010.00.

DG9298.** This station is in an area of known vertical motion. If an
DG9298.** orthometric height was ever established but is not available
DG9298.** in the current survey control section, the orthometric height
DG9298.** is considered suspect. Suspect heights are available in the
DG9298.** superseded section only if requested.
DG9298
DG9298.Significant digits in the geoid height do not necessarily reflect accuracy.

DG9298.The PID for the CORS L1 Phase Center is DL9722.

DG9298.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9298
DG9298.The ellipsoidal height was determined by GPS observations
DG9298.and is referenced to NAD 83.
