DM4157.The coordinates were established by GPS observations
DM4157.and adjusted by the National Geodetic Survey in June 2022.
DM4157
DM4157.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM4157.been affixed to the stable North American Tectonic Plate.
DM4157
DM4157.The coordinates are valid at the epoch date displayed above
DM4157.which is a decimal equivalence of Year/Month/Day.
DM4157
DM4157.Due to the release of the International GNSS Service (IGS) 2014
DM4157.realization of the International Terrestrial Reference Frame of 2014
DM4157.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM4157.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM4157.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM4157.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM4157.currently published epoch of 2010.00.
DM4157
DM4157.Additional information on MYCS2 is available at
DM4157.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM4157.Significant digits in the geoid height do not necessarily reflect accuracy.
DM4157.GEOID18 height accuracy estimate available here.

DM4157.The XYZ, and position/ellipsoidal ht. are equivalent.
DM4157
DM4157.The ellipsoidal height was determined by GPS observations
DM4157.and is referenced to NAD 83.
