DF8978.The coordinates were established by GPS observations
DF8978.and adjusted by the National Geodetic Survey in June 2019.
DF8978
DF8978.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF8978.been affixed to the stable North American Tectonic Plate.
DF8978
DF8978.The coordinates are valid at the epoch date displayed above
DF8978.which is a decimal equivalence of Year/Month/Day.
DF8978
DF8978.Due to the release of the International GNSS Service (IGS) 2014
DF8978.realization of the International Terrestrial Reference Frame of 2014
DF8978.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8978.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8978.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8978.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8978.currently published epoch of 2010.00.
DF8978
DF8978.Additional information on MYCS2 is available at
DF8978.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF8978.Significant digits in the geoid height do not necessarily reflect accuracy.
DF8978.GEOID18 height accuracy estimate available here.

DF8978
DF8978.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8978
DF8978.The ellipsoidal height was determined by GPS observations
DF8978.and is referenced to NAD 83.
