DQ6216.Formal positional accuracy estimates are not available for this CORS
DQ6216.because its coordinates were determined in part using modeled
DQ6216.velocities. Approximate one-sigma accuracies for latitude, longitude,
DQ6216.and ellipsoid height can be obtained from the short-term time series.
DQ6216.Additional information regarding modeled velocities is available on
DQ6216.the CORS Coordinates for MYCS2 web page:
DQ6216.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DQ6216
DQ6216.The coordinates were established by GPS observations
DQ6216.and adjusted by the National Geodetic Survey in August 2019.
DQ6216
DQ6216.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DQ6216.been affixed to the stable North American Tectonic Plate.
DQ6216
DQ6216.The coordinates are valid at the epoch date displayed above
DQ6216.which is a decimal equivalence of Year/Month/Day.
DQ6216
DQ6216.Due to the release of the International GNSS Service (IGS) 2014
DQ6216.realization of the International Terrestrial Reference Frame of 2014
DQ6216.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DQ6216.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DQ6216.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DQ6216.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DQ6216.currently published epoch of 2010.00.

DQ6216.Additional information on MYCS2 is available at
DQ6216.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DQ6216
DQ6216.The orthometric height was determined by GPS observations and a
DQ6216.high-resolution geoid model using precise GPS observation and
DQ6216.processing techniques.
DQ6216
DQ6216.Significant digits in the geoid height do not necessarily reflect accuracy.
DQ6216.GEOID18 height accuracy estimate available here.

DQ6216.The PID for the CORS L1 Phase Center is DQ6217.

DQ6216.Click photographs - Photos may exist for this station.
DQ6216
DQ6216.The XYZ, and position/ellipsoidal ht. are equivalent.
DQ6216
DQ6216.The ellipsoidal height was determined by GPS observations
DQ6216.and is referenced to NAD 83.
