DI1657.Formal positional accuracy estimates are not available for this CORS
DI1657.because its coordinates were determined in part using modeled
DI1657.velocities. Approximate one-sigma accuracies for latitude, longitude,
DI1657.and ellipsoid height can be obtained from the short-term time series.
DI1657.Additional information regarding modeled velocities is available on
DI1657.the CORS Coordinates for MYCS2 web page:
DI1657.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DI1657
DI1657.The coordinates were established by GPS observations
DI1657.and adjusted by the National Geodetic Survey in June 2019.
DI1657
DI1657.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI1657.been affixed to the stable North American Tectonic Plate.
DI1657
DI1657.The coordinates are valid at the epoch date displayed above
DI1657.which is a decimal equivalence of Year/Month/Day.
DI1657
DI1657.Due to the release of the International GNSS Service (IGS) 2014
DI1657.realization of the International Terrestrial Reference Frame of 2014
DI1657.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI1657.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI1657.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI1657.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI1657.currently published epoch of 2010.00.

DI1657.Additional information on MYCS2 is available at
DI1657.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DI1657
DI1657.The orthometric height was determined by GPS observations and a
DI1657.high-resolution geoid model using precise GPS observation and
DI1657.processing techniques.
DI1657
DI1657.Significant digits in the geoid height do not necessarily reflect accuracy.
DI1657.GEOID18 height accuracy estimate available here.
DI1657
DI1657.The PID for the CORS L1 Phase Center is DI1658.

DI1657.Click photographs - Photos may exist for this station.
DI1657
DI1657.The XYZ, and position/ellipsoidal ht. are equivalent.
DI1657
DI1657.The ellipsoidal height was determined by GPS observations
DI1657.and is referenced to NAD 83.
