DS1981.Formal positional accuracy estimates are not available for this CORS
DS1981.because its coordinates were determined in part using modeled
DS1981.velocities. Approximate one-sigma accuracies for latitude, longitude,
DS1981.and ellipsoid height can be obtained from the short-term time series.
DS1981.Additional information regarding modeled velocities is available on
DS1981.the CORS Coordinates for MYCS2 web page:
DS1981.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DS1981
DS1981.The coordinates were established by GPS observations
DS1981.and adjusted by the National Geodetic Survey in November 2024.
DS1981
DS1981.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DS1981.been affixed to the stable North American Tectonic Plate.
DS1981
DS1981.The coordinates are valid at the epoch date displayed above
DS1981.which is a decimal equivalence of Year/Month/Day.
DS1981
DS1981.Due to the release of the International GNSS Service (IGS) 2014
DS1981.realization of the International Terrestrial Reference Frame of 2014
DS1981.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DS1981.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DS1981.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DS1981.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DS1981.currently published epoch of 2010.00.

DS1981.** This station is in an area of known vertical motion. If an
DS1981.** orthometric height was ever established but is not available
DS1981.** in the current survey control section, the orthometric height
DS1981.** is considered suspect. Suspect heights are available in the
DS1981.** superseded section only if requested.

DS1981.Significant digits in the geoid height do not necessarily reflect accuracy.
