DP7421.Formal positional accuracy estimates are not available for this CORS
DP7421.because its coordinates were determined in part using modeled
DP7421.velocities. Approximate one-sigma accuracies for latitude, longitude,
DP7421.and ellipsoid height can be obtained from the short-term time series.
DP7421.Additional information regarding modeled velocities is available on
DP7421.the CORS Coordinates for MYCS2 web page:
DP7421.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DP7421
DP7421.The coordinates were established by GPS observations
DP7421.and adjusted by the National Geodetic Survey in June 2019.
DP7421
DP7421.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP7421.been affixed to the stable North American Tectonic Plate.
DP7421
DP7421.The coordinates are valid at the epoch date displayed above
DP7421.which is a decimal equivalence of Year/Month/Day.
DP7421
DP7421.Due to the release of the International GNSS Service (IGS) 2014
DP7421.realization of the International Terrestrial Reference Frame of 2014
DP7421.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP7421.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP7421.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP7421.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP7421.currently published epoch of 2010.00.

DP7421.** This station is in an area of known vertical motion. If an
DP7421.** orthometric height was ever established but is not available
DP7421.** in the current survey control section, the orthometric height
DP7421.** is considered suspect. Suspect heights are available in the
DP7421.** superseded section only if requested.
DP7421
DP7421.Significant digits in the geoid height do not necessarily reflect accuracy.

DP7421.The PID for the CORS L1 Phase Center is DR3639.

DP7421.Click photographs - Photos may exist for this station.
DP7421
DP7421.The XYZ, and position/ellipsoidal ht. are equivalent.
DP7421
DP7421.The ellipsoidal height was determined by GPS observations
DP7421.and is referenced to NAD 83.
