DF7986.The coordinates were established by GPS observations
DF7986.and adjusted by the National Geodetic Survey in June 2019.
DF7986
DF7986.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF7986.been affixed to the stable North American Tectonic Plate.
DF7986
DF7986.The coordinates are valid at the epoch date displayed above
DF7986.which is a decimal equivalence of Year/Month/Day.
DF7986
DF7986.Due to the release of the International GNSS Service (IGS) 2014
DF7986.realization of the International Terrestrial Reference Frame of 2014
DF7986.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF7986.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF7986.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF7986.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF7986.currently published epoch of 2010.00.
DF7986
DF7986.Additional information on MYCS2 is available at
DF7986.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF7986
DF7986.The orthometric height was determined by GPS observations and a
DF7986.high-resolution geoid model using precise GPS observation and
DF7986.processing techniques.
DF7986
DF7986.Significant digits in the geoid height do not necessarily reflect accuracy.
DF7986.GEOID18 height accuracy estimate available here.
DF7986
DF7986.The PID for the CORS L1 Phase Center is DF7987.

DF7986.Click photographs - Photos may exist for this station.
DF7986
DF7986.The XYZ, and position/ellipsoidal ht. are equivalent.
DF7986
DF7986.The ellipsoidal height was determined by GPS observations
DF7986.and is referenced to NAD 83.
