DS1975.Formal positional accuracy estimates are not available for this CORS
DS1975.because its coordinates were determined in part using modeled
DS1975.velocities. Approximate one-sigma accuracies for latitude, longitude,
DS1975.and ellipsoid height can be obtained from the short-term time series.
DS1975.Additional information regarding modeled velocities is available on
DS1975.the CORS Coordinates for MYCS2 web page:
DS1975.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DS1975
DS1975.The coordinates were established by GPS observations
DS1975.and adjusted by the National Geodetic Survey in July 2024.
DS1975
DS1975.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DS1975.been affixed to the stable North American Tectonic Plate.
DS1975
DS1975.The coordinates are valid at the epoch date displayed above
DS1975.which is a decimal equivalence of Year/Month/Day.
DS1975
DS1975.Due to the release of the International GNSS Service (IGS) 2014
DS1975.realization of the International Terrestrial Reference Frame of 2014
DS1975.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DS1975.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DS1975.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DS1975.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DS1975.currently published epoch of 2010.00.

DS1975.The XYZ, and position/ellipsoidal ht. are equivalent.
DS1975
DS1975.The ellipsoidal height was determined by GPS observations
DS1975.and is referenced to NAD 83.
