DF8970.The coordinates were established by GPS observations
DF8970.and adjusted by the National Geodetic Survey in June 2019.
DF8970
DF8970.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF8970.been affixed to the stable North American Tectonic Plate.
DF8970
DF8970.The coordinates are valid at the epoch date displayed above
DF8970.which is a decimal equivalence of Year/Month/Day.
DF8970
DF8970.Due to the release of the International GNSS Service (IGS) 2014
DF8970.realization of the International Terrestrial Reference Frame of 2014
DF8970.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8970.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8970.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8970.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8970.currently published epoch of 2010.00.
DF8970
DF8970.Additional information on MYCS2 is available at
DF8970.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF8970.Significant digits in the geoid height do not necessarily reflect accuracy.
DF8970.GEOID18 height accuracy estimate available here.

DF8970.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8970
DF8970.The ellipsoidal height was determined by GPS observations
DF8970.and is referenced to NAD 83.
