DP2481.Formal positional accuracy estimates are not available for this CORS
DP2481.because its coordinates were determined in part using modeled
DP2481.velocities. Approximate one-sigma accuracies for latitude, longitude,
DP2481.and ellipsoid height can be obtained from the short-term time series.
DP2481.Additional information regarding modeled velocities is available on
DP2481.the CORS Coordinates for MYCS2 web page:
DP2481.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DP2481
DP2481.The coordinates were established by GPS observations
DP2481.and adjusted by the National Geodetic Survey in June 2019.
DP2481
DP2481.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP2481.been affixed to the stable North American Tectonic Plate.
DP2481
DP2481.The coordinates are valid at the epoch date displayed above
DP2481.which is a decimal equivalence of Year/Month/Day.
DP2481
DP2481.Due to the release of the International GNSS Service (IGS) 2014
DP2481.realization of the International Terrestrial Reference Frame of 2014
DP2481.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP2481.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP2481.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP2481.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP2481.currently published epoch of 2010.00.

DP2481.The orthometric height was determined by GPS observations and a
DP2481.high-resolution geoid model using precise GPS observation and
DP2481.processing techniques.
DP2481
DP2481.Significant digits in the geoid height do not necessarily reflect accuracy.
DP2481.GEOID18 height accuracy estimate available here.

DP2481.Click photographs - Photos may exist for this station.
DP2481
DP2481.The XYZ, and position/ellipsoidal ht. are equivalent.
DP2481
DP2481.The ellipsoidal height was determined by GPS observations
DP2481.and is referenced to NAD 83.
