DM5371.The coordinates were established by GPS observations
DM5371.and adjusted by the National Geodetic Survey in June 2019.
DM5371
DM5371.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM5371.been affixed to the stable North American Tectonic Plate.
DM5371
DM5371.The coordinates are valid at the epoch date displayed above
DM5371.which is a decimal equivalence of Year/Month/Day.
DM5371
DM5371.Due to the release of the International GNSS Service (IGS) 2014
DM5371.realization of the International Terrestrial Reference Frame of 2014
DM5371.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM5371.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM5371.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM5371.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM5371.currently published epoch of 2010.00.
DM5371
DM5371.Additional information on MYCS2 is available at
DM5371.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM5371.Significant digits in the geoid height do not necessarily reflect accuracy.
DM5371.GEOID18 height accuracy estimate available here.

DM5371.The XYZ, and position/ellipsoidal ht. are equivalent.
DM5371
DM5371.The ellipsoidal height was determined by GPS observations
DM5371.and is referenced to NAD 83.
