DL3502.Formal positional accuracy estimates are not available for this CORS
DL3502.because its coordinates were determined in part using modeled
DL3502.velocities. Approximate one-sigma accuracies for latitude, longitude,
DL3502.and ellipsoid height can be obtained from the short-term time series.
DL3502.Additional information regarding modeled velocities is available on
DL3502.the CORS Coordinates for MYCS2 web page:
DL3502.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DL3502
DL3502.The coordinates were established by GPS observations
DL3502.and adjusted by the National Geodetic Survey in June 2019.
DL3502
DL3502.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3502.been affixed to the stable North American Tectonic Plate.
DL3502
DL3502.The coordinates are valid at the epoch date displayed above
DL3502.which is a decimal equivalence of Year/Month/Day.
DL3502
DL3502.Due to the release of the International GNSS Service (IGS) 2014
DL3502.realization of the International Terrestrial Reference Frame of 2014
DL3502.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3502.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3502.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3502.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3502.currently published epoch of 2010.00.

DL3502.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3502
DL3502.The ellipsoidal height was determined by GPS observations
DL3502.and is referenced to NAD 83.
