DL7728.The coordinates were established by GPS observations
DL7728.and adjusted by the National Geodetic Survey in December 2022.
DL7728
DL7728.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7728.been affixed to the stable North American Tectonic Plate.
DL7728
DL7728.The coordinates are valid at the epoch date displayed above
DL7728.which is a decimal equivalence of Year/Month/Day.
DL7728
DL7728.Due to the release of the International GNSS Service (IGS) 2014
DL7728.realization of the International Terrestrial Reference Frame of 2014
DL7728.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7728.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7728.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7728.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7728.currently published epoch of 2010.00.
DL7728
DL7728.Additional information on MYCS2 is available at
DL7728.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL7728.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7728
DL7728.The ellipsoidal height was determined by GPS observations
DL7728.and is referenced to NAD 83.
