DI0731.The coordinates were established by GPS observations
DI0731.and adjusted by the National Geodetic Survey in June 2019.
DI0731
DI0731.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI0731.been affixed to the stable North American Tectonic Plate.
DI0731
DI0731.The coordinates are valid at the epoch date displayed above
DI0731.which is a decimal equivalence of Year/Month/Day.
DI0731
DI0731.Due to the release of the International GNSS Service (IGS) 2014
DI0731.realization of the International Terrestrial Reference Frame of 2014
DI0731.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI0731.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI0731.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI0731.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI0731.currently published epoch of 2010.00.
DI0731
DI0731.Additional information on MYCS2 is available at
DI0731.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI0731.Significant digits in the geoid height do not necessarily reflect accuracy.
DI0731.GEOID18 height accuracy estimate available here.

DI0731.The XYZ, and position/ellipsoidal ht. are equivalent.
DI0731
DI0731.The ellipsoidal height was determined by GPS observations
DI0731.and is referenced to NAD 83.
