DI8418.The coordinates were established by GPS observations
DI8418.and adjusted by the National Geodetic Survey in June 2019.
DI8418
DI8418.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI8418.been affixed to the stable North American Tectonic Plate.
DI8418
DI8418.The coordinates are valid at the epoch date displayed above
DI8418.which is a decimal equivalence of Year/Month/Day.
DI8418
DI8418.Due to the release of the International GNSS Service (IGS) 2014
DI8418.realization of the International Terrestrial Reference Frame of 2014
DI8418.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI8418.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI8418.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI8418.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI8418.currently published epoch of 2010.00.
DI8418
DI8418.Additional information on MYCS2 is available at
DI8418.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI8418.Significant digits in the geoid height do not necessarily reflect accuracy.
DI8418.GEOID18 height accuracy estimate available here.

DI8418.The XYZ, and position/ellipsoidal ht. are equivalent.
DI8418
DI8418.The ellipsoidal height was determined by GPS observations
DI8418.and is referenced to NAD 83.
