DL6456.The coordinates were established by GPS observations
DL6456.and adjusted by the National Geodetic Survey in February 2020.
DL6456
DL6456.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6456.been affixed to the stable North American Tectonic Plate.
DL6456
DL6456.The coordinates are valid at the epoch date displayed above
DL6456.which is a decimal equivalence of Year/Month/Day.
DL6456
DL6456.Due to the release of the International GNSS Service (IGS) 2014
DL6456.realization of the International Terrestrial Reference Frame of 2014
DL6456.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6456.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6456.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6456.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6456.currently published epoch of 2010.00.
DL6456
DL6456.Additional information on MYCS2 is available at
DL6456.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL6456.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6456
DL6456.The ellipsoidal height was determined by GPS observations
DL6456.and is referenced to NAD 83.
