DF7048.The coordinates were established by GPS observations
DF7048.and adjusted by the National Geodetic Survey in June 2019.
DF7048
DF7048.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF7048.been affixed to the stable North American Tectonic Plate.
DF7048
DF7048.The coordinates are valid at the epoch date displayed above
DF7048.which is a decimal equivalence of Year/Month/Day.
DF7048
DF7048.Due to the release of the International GNSS Service (IGS) 2014
DF7048.realization of the International Terrestrial Reference Frame of 2014
DF7048.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF7048.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF7048.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF7048.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF7048.currently published epoch of 2010.00.
DF7048
DF7048.Additional information on MYCS2 is available at
DF7048.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF7048
DF7048.The orthometric height was determined by GPS observations and a
DF7048.high-resolution geoid model using precise GPS observation and
DF7048.processing techniques.
DF7048
DF7048.Significant digits in the geoid height do not necessarily reflect accuracy.
DF7048.GEOID18 height accuracy estimate available here.
DF7048
DF7048.The PID for the CORS L1 Phase Center is DR3562.

DF7048.Click photographs - Photos may exist for this station.
DF7048
DF7048.The XYZ, and position/ellipsoidal ht. are equivalent.
DF7048
DF7048.The ellipsoidal height was determined by GPS observations
DF7048.and is referenced to NAD 83.
