DF7990.The coordinates were established by GPS observations
DF7990.and adjusted by the National Geodetic Survey in June 2019.
DF7990
DF7990.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF7990.been affixed to the stable North American Tectonic Plate.
DF7990
DF7990.The coordinates are valid at the epoch date displayed above
DF7990.which is a decimal equivalence of Year/Month/Day.
DF7990
DF7990.Due to the release of the International GNSS Service (IGS) 2014
DF7990.realization of the International Terrestrial Reference Frame of 2014
DF7990.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF7990.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF7990.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF7990.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF7990.currently published epoch of 2010.00.
DF7990
DF7990.Additional information on MYCS2 is available at
DF7990.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF7990
DF7990.The orthometric height was determined by differential leveling and
DF7990.adjusted by the NATIONAL GEODETIC SURVEY
DF7990.in April 2016.
DF7990
DF7990.Significant digits in the geoid height do not necessarily reflect accuracy.
DF7990.GEOID18 height accuracy estimate available here.

DF7990.The PID for the CORS L1 Phase Center is DO9892.

DF7990.Click photographs - Photos may exist for this station.
DF7990
DF7990.The XYZ, and position/ellipsoidal ht. are equivalent.
DF7990
DF7990.The ellipsoidal height was determined by GPS observations
DF7990.and is referenced to NAD 83.
