DM2700.Formal positional accuracy estimates are not available for this CORS
DM2700.because its coordinates were determined in part using modeled
DM2700.velocities. Approximate one-sigma accuracies for latitude, longitude,
DM2700.and ellipsoid height can be obtained from the short-term time series.
DM2700.Additional information regarding modeled velocities is available on
DM2700.the CORS Coordinates for MYCS2 web page:
DM2700.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DM2700
DM2700.The coordinates were established by GPS observations
DM2700.and adjusted by the National Geodetic Survey in March 2024.
DM2700
DM2700.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM2700.been affixed to the stable North American Tectonic Plate.
DM2700
DM2700.The coordinates are valid at the epoch date displayed above
DM2700.which is a decimal equivalence of Year/Month/Day.
DM2700
DM2700.Due to the release of the International GNSS Service (IGS) 2014
DM2700.realization of the International Terrestrial Reference Frame of 2014
DM2700.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM2700.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM2700.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM2700.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM2700.currently published epoch of 2010.00.

DM2700.The XYZ, and position/ellipsoidal ht. are equivalent.
DM2700
DM2700.The ellipsoidal height was determined by GPS observations
DM2700.and is referenced to NAD 83.
