DM7872.The coordinates were established by GPS observations
DM7872.and adjusted by the National Geodetic Survey in January 2023.
DM7872
DM7872.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7872.been affixed to the stable North American Tectonic Plate.
DM7872
DM7872.The coordinates are valid at the epoch date displayed above
DM7872.which is a decimal equivalence of Year/Month/Day.
DM7872
DM7872.Due to the release of the International GNSS Service (IGS) 2014
DM7872.realization of the International Terrestrial Reference Frame of 2014
DM7872.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7872.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7872.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7872.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7872.currently published epoch of 2010.00.
DM7872
DM7872.Additional information on MYCS2 is available at
DM7872.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM7872.Significant digits in the geoid height do not necessarily reflect accuracy.

DM7872.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7872
DM7872.The ellipsoidal height was determined by GPS observations
DM7872.and is referenced to NAD 83.
