DI1085.The coordinates were established by GPS observations
DI1085.and adjusted by the National Geodetic Survey in June 2019.
DI1085
DI1085.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI1085.been affixed to the stable North American Tectonic Plate.
DI1085
DI1085.The coordinates are valid at the epoch date displayed above
DI1085.which is a decimal equivalence of Year/Month/Day.
DI1085
DI1085.Due to the release of the International GNSS Service (IGS) 2014
DI1085.realization of the International Terrestrial Reference Frame of 2014
DI1085.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI1085.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI1085.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI1085.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI1085.currently published epoch of 2010.00.
DI1085
DI1085.Additional information on MYCS2 is available at
DI1085.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI1085.Significant digits in the geoid height do not necessarily reflect accuracy.
DI1085.GEOID18 height accuracy estimate available here.

DI1085
DI1085.The XYZ, and position/ellipsoidal ht. are equivalent.
DI1085
DI1085.The ellipsoidal height was determined by GPS observations
DI1085.and is referenced to NAD 83.
