DM7487.The coordinates were established by GPS observations
DM7487.and adjusted by the National Geodetic Survey in September 2021.
DM7487
DM7487.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7487.been affixed to the stable North American Tectonic Plate.
DM7487
DM7487.The coordinates are valid at the epoch date displayed above
DM7487.which is a decimal equivalence of Year/Month/Day.
DM7487
DM7487.Due to the release of the International GNSS Service (IGS) 2014
DM7487.realization of the International Terrestrial Reference Frame of 2014
DM7487.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7487.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7487.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7487.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7487.currently published epoch of 2010.00.
DM7487
DM7487.Additional information on MYCS2 is available at
DM7487.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM7487.Significant digits in the geoid height do not necessarily reflect accuracy.
DM7487.GEOID12B height accuracy estimate available here.

DM7487.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7487
DM7487.The ellipsoidal height was determined by GPS observations
DM7487.and is referenced to NAD 83.
