DF8990.The coordinates were established by GPS observations
DF8990.and adjusted by the National Geodetic Survey in June 2019.
DF8990
DF8990.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF8990.been affixed to the stable North American Tectonic Plate.
DF8990
DF8990.The coordinates are valid at the epoch date displayed above
DF8990.which is a decimal equivalence of Year/Month/Day.
DF8990
DF8990.Due to the release of the International GNSS Service (IGS) 2014
DF8990.realization of the International Terrestrial Reference Frame of 2014
DF8990.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8990.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8990.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8990.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8990.currently published epoch of 2010.00.
DF8990
DF8990.Additional information on MYCS2 is available at
DF8990.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF8990.Significant digits in the geoid height do not necessarily reflect accuracy.
DF8990.GEOID18 height accuracy estimate available here.

DF8990.Click photographs - Photos may exist for this station.
DF8990
DF8990.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8990
DF8990.The ellipsoidal height was determined by GPS observations
DF8990.and is referenced to NAD 83.
