DG5940.The coordinates were established by GPS observations
DG5940.and adjusted by the National Geodetic Survey in June 2019.
DG5940
DG5940.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG5940.been affixed to the stable North American Tectonic Plate.
DG5940
DG5940.The coordinates are valid at the epoch date displayed above
DG5940.which is a decimal equivalence of Year/Month/Day.
DG5940
DG5940.Due to the release of the International GNSS Service (IGS) 2014
DG5940.realization of the International Terrestrial Reference Frame of 2014
DG5940.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG5940.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG5940.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG5940.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG5940.currently published epoch of 2010.00.
DG5940
DG5940.Additional information on MYCS2 is available at
DG5940.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DG5940.Significant digits in the geoid height do not necessarily reflect accuracy.
DG5940.GEOID18 height accuracy estimate available here.

DG5940.The XYZ, and position/ellipsoidal ht. are equivalent.
DG5940
DG5940.The ellipsoidal height was determined by GPS observations
DG5940.and is referenced to NAD 83.
