DI4161.The coordinates were established by GPS observations
DI4161.and adjusted by the National Geodetic Survey in June 2019.
DI4161
DI4161.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI4161.been affixed to the stable North American Tectonic Plate.
DI4161
DI4161.The coordinates are valid at the epoch date displayed above
DI4161.which is a decimal equivalence of Year/Month/Day.
DI4161
DI4161.Due to the release of the International GNSS Service (IGS) 2014
DI4161.realization of the International Terrestrial Reference Frame of 2014
DI4161.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI4161.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI4161.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI4161.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI4161.currently published epoch of 2010.00.
DI4161
DI4161.Additional information on MYCS2 is available at
DI4161.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI4161.Significant digits in the geoid height do not necessarily reflect accuracy.
DI4161.GEOID18 height accuracy estimate available here.

DI4161.The XYZ, and position/ellipsoidal ht. are equivalent.
DI4161
DI4161.The ellipsoidal height was determined by GPS observations
DI4161.and is referenced to NAD 83.
