DM5369.Formal positional accuracy estimates are not available for this CORS
DM5369.because its coordinates were determined in part using modeled
DM5369.velocities. Approximate one-sigma accuracies for latitude, longitude,
DM5369.and ellipsoid height can be obtained from the short-term time series.
DM5369.Additional information regarding modeled velocities is available on
DM5369.the CORS Coordinates for MYCS2 web page:
DM5369.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DM5369
DM5369.The coordinates were established by GPS observations
DM5369.and adjusted by the National Geodetic Survey in June 2019.
DM5369
DM5369.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM5369.been affixed to the stable North American Tectonic Plate.
DM5369
DM5369.The coordinates are valid at the epoch date displayed above
DM5369.which is a decimal equivalence of Year/Month/Day.
DM5369
DM5369.Due to the release of the International GNSS Service (IGS) 2014
DM5369.realization of the International Terrestrial Reference Frame of 2014
DM5369.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM5369.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM5369.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM5369.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM5369.currently published epoch of 2010.00.

DM5369.** This station is in an area of known vertical motion. If an
DM5369.** orthometric height was ever established but is not available
DM5369.** in the current survey control section, the orthometric height
DM5369.** is considered suspect. Suspect heights are available in the
DM5369.** superseded section only if requested.
DM5369
DM5369.Significant digits in the geoid height do not necessarily reflect accuracy.
DM5369.GEOID18 height accuracy estimate available here.
DM5369
DM5369.The PID for the CORS L1 Phase Center is DM5370.

DM5369
DM5369.The XYZ, and position/ellipsoidal ht. are equivalent.
DM5369
DM5369.The ellipsoidal height was determined by GPS observations
DM5369.and is referenced to NAD 83.
