DI8428.The coordinates were established by GPS observations
DI8428.and adjusted by the National Geodetic Survey in June 2019.
DI8428
DI8428.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI8428.been affixed to the stable North American Tectonic Plate.
DI8428
DI8428.The coordinates are valid at the epoch date displayed above
DI8428.which is a decimal equivalence of Year/Month/Day.
DI8428
DI8428.Due to the release of the International GNSS Service (IGS) 2014
DI8428.realization of the International Terrestrial Reference Frame of 2014
DI8428.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI8428.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI8428.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI8428.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI8428.currently published epoch of 2010.00.
DI8428
DI8428.Additional information on MYCS2 is available at
DI8428.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI8428.Significant digits in the geoid height do not necessarily reflect accuracy.
DI8428.GEOID18 height accuracy estimate available here.

DI8428
DI8428.The XYZ, and position/ellipsoidal ht. are equivalent.
DI8428
DI8428.The ellipsoidal height was determined by GPS observations
DI8428.and is referenced to NAD 83.
