DI2257.The coordinates were established by GPS observations
DI2257.and adjusted by the National Geodetic Survey in June 2019.
DI2257
DI2257.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI2257.been affixed to the stable North American Tectonic Plate.
DI2257
DI2257.The coordinates are valid at the epoch date displayed above
DI2257.which is a decimal equivalence of Year/Month/Day.
DI2257
DI2257.Due to the release of the International GNSS Service (IGS) 2014
DI2257.realization of the International Terrestrial Reference Frame of 2014
DI2257.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI2257.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI2257.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI2257.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI2257.currently published epoch of 2010.00.
DI2257
DI2257.Additional information on MYCS2 is available at
DI2257.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI2257.Significant digits in the geoid height do not necessarily reflect accuracy.
DI2257.GEOID18 height accuracy estimate available here.

DI2257
DI2257.The XYZ, and position/ellipsoidal ht. are equivalent.
DI2257
DI2257.The ellipsoidal height was determined by GPS observations
DI2257.and is referenced to NAD 83.
