DF8481.Formal positional accuracy estimates are not available for this CORS
DF8481.because its coordinates were determined in part using modeled
DF8481.velocities. Approximate one-sigma accuracies for latitude, longitude,
DF8481.and ellipsoid height can be obtained from the short-term time series.
DF8481.Additional information regarding modeled velocities is available on
DF8481.the CORS Coordinates for MYCS2 web page:
DF8481.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DF8481
DF8481.The coordinates were established by GPS observations
DF8481.and adjusted by the National Geodetic Survey in October 2003.
DF8481
DF8481.The datum tag of NAD 83(CORS) is equivalent to NAD 83(CORS96).
DF8481
DF8481.The coordinates are valid at the epoch date displayed above
DF8481.which is a decimal equivalence of Year/Month/Day.
DF8481
DF8481.Due to the release of the International GNSS Service (IGS) 2014
DF8481.realization of the International Terrestrial Reference Frame of 2014
DF8481.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8481.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8481.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8481.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8481.currently published epoch of 2010.00.

DF8481.The orthometric height was determined by differential leveling and
DF8481.adjusted by the NATIONAL GEODETIC SURVEY
DF8481.in February 2020.
DF8481
DF8481.Significant digits in the geoid height do not necessarily reflect accuracy.

DF8481.Click photographs - Photos may exist for this station.
DF8481
DF8481.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8481
DF8481.The ellipsoidal height was determined by GPS observations
DF8481.and is referenced to NAD 83.
