DL9812.The coordinates were established by GPS observations
DL9812.and adjusted by the National Geodetic Survey in April 2022.
DL9812
DL9812.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL9812.been affixed to the stable North American Tectonic Plate.
DL9812
DL9812.The coordinates are valid at the epoch date displayed above
DL9812.which is a decimal equivalence of Year/Month/Day.
DL9812
DL9812.Due to the release of the International GNSS Service (IGS) 2014
DL9812.realization of the International Terrestrial Reference Frame of 2014
DL9812.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL9812.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL9812.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL9812.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL9812.currently published epoch of 2010.00.
DL9812
DL9812.Additional information on MYCS2 is available at
DL9812.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL9812.Significant digits in the geoid height do not necessarily reflect accuracy.
DL9812.GEOID18 height accuracy estimate available here.

DL9812.The XYZ, and position/ellipsoidal ht. are equivalent.
DL9812
DL9812.The ellipsoidal height was determined by GPS observations
DL9812.and is referenced to NAD 83.
