DL7725.The coordinates were established by GPS observations
DL7725.and adjusted by the National Geodetic Survey in June 2019.
DL7725
DL7725.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7725.been affixed to the stable North American Tectonic Plate.
DL7725
DL7725.The coordinates are valid at the epoch date displayed above
DL7725.which is a decimal equivalence of Year/Month/Day.
DL7725
DL7725.Due to the release of the International GNSS Service (IGS) 2014
DL7725.realization of the International Terrestrial Reference Frame of 2014
DL7725.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7725.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7725.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7725.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7725.currently published epoch of 2010.00.
DL7725
DL7725.Additional information on MYCS2 is available at
DL7725.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL7725.Significant digits in the geoid height do not necessarily reflect accuracy.
DL7725.GEOID18 height accuracy estimate available here.

DL7725.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7725
DL7725.The ellipsoidal height was determined by GPS observations
DL7725.and is referenced to NAD 83.
