DI2212.The coordinates were established by GPS observations
DI2212.and adjusted by the National Geodetic Survey in June 2019.
DI2212
DI2212.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI2212.been affixed to the stable North American Tectonic Plate.
DI2212
DI2212.The coordinates are valid at the epoch date displayed above
DI2212.which is a decimal equivalence of Year/Month/Day.
DI2212
DI2212.Due to the release of the International GNSS Service (IGS) 2014
DI2212.realization of the International Terrestrial Reference Frame of 2014
DI2212.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI2212.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI2212.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI2212.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI2212.currently published epoch of 2010.00.
DI2212
DI2212.Additional information on MYCS2 is available at
DI2212.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI2212.Significant digits in the geoid height do not necessarily reflect accuracy.
DI2212.GEOID18 height accuracy estimate available here.

DI2212.The XYZ, and position/ellipsoidal ht. are equivalent.
DI2212
DI2212.The ellipsoidal height was determined by GPS observations
DI2212.and is referenced to NAD 83.
