DM3967.Formal positional accuracy estimates are not available for this CORS
DM3967.because its coordinates were determined in part using modeled
DM3967.velocities. Approximate one-sigma accuracies for latitude, longitude,
DM3967.and ellipsoid height can be obtained from the short-term time series.
DM3967.Additional information regarding modeled velocities is available on
DM3967.the CORS Coordinates for MYCS2 web page:
DM3967.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DM3967
DM3967.The coordinates were established by GPS observations
DM3967.and adjusted by the National Geodetic Survey in June 2019.
DM3967
DM3967.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM3967.been affixed to the stable North American Tectonic Plate.
DM3967
DM3967.The coordinates are valid at the epoch date displayed above
DM3967.which is a decimal equivalence of Year/Month/Day.
DM3967
DM3967.Due to the release of the International GNSS Service (IGS) 2014
DM3967.realization of the International Terrestrial Reference Frame of 2014
DM3967.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM3967.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM3967.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM3967.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM3967.currently published epoch of 2010.00.

DM3967
DM3967.The orthometric height was determined by differential leveling and
DM3967.adjusted by the NATIONAL GEODETIC SURVEY
DM3967.in December 2011.
DM3967
DM3967.No vertical observational check was made to the station.
DM3967
DM3967.Significant digits in the geoid height do not necessarily reflect accuracy.
DM3967.GEOID18 height accuracy estimate available here.
DM3967
DM3967.The PID for the CORS L1 Phase Center is DM3968.

DM3967.Click photographs - Photos may exist for this station.
DM3967
DM3967.The XYZ, and position/ellipsoidal ht. are equivalent.
DM3967
DM3967.The ellipsoidal height was determined by GPS observations
DM3967.and is referenced to NAD 83.
