DM7506.The coordinates were established by GPS observations
DM7506.and adjusted by the National Geodetic Survey in May 2021.
DM7506
DM7506.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7506.been affixed to the stable North American Tectonic Plate.
DM7506
DM7506.The coordinates are valid at the epoch date displayed above
DM7506.which is a decimal equivalence of Year/Month/Day.
DM7506
DM7506.Due to the release of the International GNSS Service (IGS) 2014
DM7506.realization of the International Terrestrial Reference Frame of 2014
DM7506.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7506.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7506.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7506.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7506.currently published epoch of 2010.00.
DM7506
DM7506.Additional information on MYCS2 is available at
DM7506.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM7506.Significant digits in the geoid height do not necessarily reflect accuracy.
DM7506.GEOID18 height accuracy estimate available here.

DM7506.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7506
DM7506.The ellipsoidal height was determined by GPS observations
DM7506.and is referenced to NAD 83.
