DI4036.The coordinates were established by GPS observations
DI4036.and adjusted by the National Geodetic Survey in June 2019.
DI4036
DI4036.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI4036.been affixed to the stable North American Tectonic Plate.
DI4036
DI4036.The coordinates are valid at the epoch date displayed above
DI4036.which is a decimal equivalence of Year/Month/Day.
DI4036
DI4036.Due to the release of the International GNSS Service (IGS) 2014
DI4036.realization of the International Terrestrial Reference Frame of 2014
DI4036.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI4036.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI4036.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI4036.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI4036.currently published epoch of 2010.00.
DI4036
DI4036.Additional information on MYCS2 is available at
DI4036.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI4036.Significant digits in the geoid height do not necessarily reflect accuracy.
DI4036.GEOID18 height accuracy estimate available here.

DI4036
DI4036.The XYZ, and position/ellipsoidal ht. are equivalent.
DI4036
DI4036.The ellipsoidal height was determined by GPS observations
DI4036.and is referenced to NAD 83.
