DM3511.Formal positional accuracy estimates are not available for this CORS
DM3511.because its coordinates were determined in part using modeled
DM3511.velocities. Approximate one-sigma accuracies for latitude, longitude,
DM3511.and ellipsoid height can be obtained from the short-term time series.
DM3511.Additional information regarding modeled velocities is available on
DM3511.the CORS Coordinates for MYCS2 web page:
DM3511.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DM3511
DM3511.The coordinates were established by GPS observations
DM3511.and adjusted by the National Geodetic Survey in June 2019.
DM3511
DM3511.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM3511.been affixed to the stable North American Tectonic Plate.
DM3511
DM3511.The coordinates are valid at the epoch date displayed above
DM3511.which is a decimal equivalence of Year/Month/Day.
DM3511
DM3511.Due to the release of the International GNSS Service (IGS) 2014
DM3511.realization of the International Terrestrial Reference Frame of 2014
DM3511.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM3511.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM3511.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM3511.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM3511.currently published epoch of 2010.00.

DM3511.The XYZ, and position/ellipsoidal ht. are equivalent.
DM3511
DM3511.The ellipsoidal height was determined by GPS observations
DM3511.and is referenced to NAD 83.
