DI1874.The coordinates were established by GPS observations
DI1874.and adjusted by the National Geodetic Survey in June 2019.
DI1874
DI1874.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI1874.been affixed to the stable North American Tectonic Plate.
DI1874
DI1874.The coordinates are valid at the epoch date displayed above
DI1874.which is a decimal equivalence of Year/Month/Day.
DI1874
DI1874.Due to the release of the International GNSS Service (IGS) 2014
DI1874.realization of the International Terrestrial Reference Frame of 2014
DI1874.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI1874.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI1874.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI1874.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI1874.currently published epoch of 2010.00.
DI1874
DI1874.Additional information on MYCS2 is available at
DI1874.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI1874.Significant digits in the geoid height do not necessarily reflect accuracy.
DI1874.GEOID18 height accuracy estimate available here.

DI1874.The XYZ, and position/ellipsoidal ht. are equivalent.
DI1874
DI1874.The ellipsoidal height was determined by GPS observations
DI1874.and is referenced to NAD 83.
