DN9085.The coordinates were established by GPS observations
DN9085.and adjusted by the National Geodetic Survey in June 2019.
DN9085
DN9085.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN9085.been affixed to the stable North American Tectonic Plate.
DN9085
DN9085.The coordinates are valid at the epoch date displayed above
DN9085.which is a decimal equivalence of Year/Month/Day.
DN9085
DN9085.Due to the release of the International GNSS Service (IGS) 2014
DN9085.realization of the International Terrestrial Reference Frame of 2014
DN9085.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN9085.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN9085.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN9085.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN9085.currently published epoch of 2010.00.
DN9085
DN9085.Additional information on MYCS2 is available at
DN9085.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DN9085
DN9085.The orthometric height was determined by GPS observations and a
DN9085.high-resolution geoid model using precise GPS observation and
DN9085.processing techniques.
DN9085
DN9085.Significant digits in the geoid height do not necessarily reflect accuracy.
DN9085.GEOID18 height accuracy estimate available here.
DN9085
DN9085.The PID for the CORS L1 Phase Center is DS2750.

DN9085.Click photographs - Photos may exist for this station.
DN9085
DN9085.The XYZ, and position/ellipsoidal ht. are equivalent.
DN9085
DN9085.The ellipsoidal height was determined by GPS observations
DN9085.and is referenced to NAD 83.
