DF9211.The coordinates were established by GPS observations
DF9211.and adjusted by the National Geodetic Survey in May 2021.
DF9211
DF9211.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF9211.been affixed to the stable North American Tectonic Plate.
DF9211
DF9211.The coordinates are valid at the epoch date displayed above
DF9211.which is a decimal equivalence of Year/Month/Day.
DF9211
DF9211.Due to the release of the International GNSS Service (IGS) 2014
DF9211.realization of the International Terrestrial Reference Frame of 2014
DF9211.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF9211.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF9211.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF9211.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF9211.currently published epoch of 2010.00.
DF9211
DF9211.Additional information on MYCS2 is available at
DF9211.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF9211
DF9211.The orthometric height was determined by GPS observations and a
DF9211.high-resolution geoid model using precise GPS observation and
DF9211.processing techniques.
DF9211
DF9211.Significant digits in the geoid height do not necessarily reflect accuracy.
DF9211.GEOID18 height accuracy estimate available here.
DF9211
DF9211.The PID for the CORS L1 Phase Center is DR1469.

DF9211.Click photographs - Photos may exist for this station.
DF9211
DF9211.The XYZ, and position/ellipsoidal ht. are equivalent.
DF9211
DF9211.The ellipsoidal height was determined by GPS observations
DF9211.and is referenced to NAD 83.
