DM3999.The coordinates were established by GPS observations
DM3999.and adjusted by the National Geodetic Survey in June 2019.
DM3999
DM3999.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM3999.been affixed to the stable North American Tectonic Plate.
DM3999
DM3999.The coordinates are valid at the epoch date displayed above
DM3999.which is a decimal equivalence of Year/Month/Day.
DM3999
DM3999.Due to the release of the International GNSS Service (IGS) 2014
DM3999.realization of the International Terrestrial Reference Frame of 2014
DM3999.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM3999.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM3999.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM3999.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM3999.currently published epoch of 2010.00.
DM3999
DM3999.Additional information on MYCS2 is available at
DM3999.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM3999.Significant digits in the geoid height do not necessarily reflect accuracy.
DM3999.GEOID18 height accuracy estimate available here.

DM3999.The XYZ, and position/ellipsoidal ht. are equivalent.
DM3999
DM3999.The ellipsoidal height was determined by GPS observations
DM3999.and is referenced to NAD 83.
