DF4070.The coordinates were established by GPS observations
DF4070.and adjusted by the National Geodetic Survey in June 2019.
DF4070
DF4070.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF4070.been affixed to the stable North American Tectonic Plate.
DF4070
DF4070.The coordinates are valid at the epoch date displayed above
DF4070.which is a decimal equivalence of Year/Month/Day.
DF4070
DF4070.Due to the release of the International GNSS Service (IGS) 2014
DF4070.realization of the International Terrestrial Reference Frame of 2014
DF4070.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF4070.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF4070.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF4070.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF4070.currently published epoch of 2010.00.
DF4070
DF4070.Additional information on MYCS2 is available at
DF4070.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF4070.Significant digits in the geoid height do not necessarily reflect accuracy.
DF4070.GEOID18 height accuracy estimate available here.

DF4070.The XYZ, and position/ellipsoidal ht. are equivalent.
DF4070
DF4070.The ellipsoidal height was determined by GPS observations
DF4070.and is referenced to NAD 83.
