DI8426.The coordinates were established by GPS observations
DI8426.and adjusted by the National Geodetic Survey in June 2019.
DI8426
DI8426.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI8426.been affixed to the stable North American Tectonic Plate.
DI8426
DI8426.The coordinates are valid at the epoch date displayed above
DI8426.which is a decimal equivalence of Year/Month/Day.
DI8426
DI8426.Due to the release of the International GNSS Service (IGS) 2014
DI8426.realization of the International Terrestrial Reference Frame of 2014
DI8426.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI8426.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI8426.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI8426.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI8426.currently published epoch of 2010.00.
DI8426
DI8426.Additional information on MYCS2 is available at
DI8426.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI8426.Significant digits in the geoid height do not necessarily reflect accuracy.
DI8426.GEOID18 height accuracy estimate available here.

DI8426
DI8426.The XYZ, and position/ellipsoidal ht. are equivalent.
DI8426
DI8426.The ellipsoidal height was determined by GPS observations
DI8426.and is referenced to NAD 83.
