DI8414.The coordinates were established by GPS observations
DI8414.and adjusted by the National Geodetic Survey in June 2019.
DI8414
DI8414.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI8414.been affixed to the stable North American Tectonic Plate.
DI8414
DI8414.The coordinates are valid at the epoch date displayed above
DI8414.which is a decimal equivalence of Year/Month/Day.
DI8414
DI8414.Due to the release of the International GNSS Service (IGS) 2014
DI8414.realization of the International Terrestrial Reference Frame of 2014
DI8414.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI8414.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI8414.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI8414.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI8414.currently published epoch of 2010.00.
DI8414
DI8414.Additional information on MYCS2 is available at
DI8414.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI8414.Significant digits in the geoid height do not necessarily reflect accuracy.
DI8414.GEOID18 height accuracy estimate available here.

DI8414.The XYZ, and position/ellipsoidal ht. are equivalent.
DI8414
DI8414.The ellipsoidal height was determined by GPS observations
DI8414.and is referenced to NAD 83.
