DN2580.The coordinates were established by GPS observations
DN2580.and adjusted by the National Geodetic Survey in June 2019.
DN2580
DN2580.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN2580.been affixed to the stable North American Tectonic Plate.
DN2580
DN2580.The coordinates are valid at the epoch date displayed above
DN2580.which is a decimal equivalence of Year/Month/Day.
DN2580
DN2580.Due to the release of the International GNSS Service (IGS) 2014
DN2580.realization of the International Terrestrial Reference Frame of 2014
DN2580.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN2580.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN2580.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN2580.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN2580.currently published epoch of 2010.00.
DN2580
DN2580.Additional information on MYCS2 is available at
DN2580.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DN2580
DN2580.The orthometric height was determined by differential leveling and
DN2580.adjusted by the NATIONAL GEODETIC SURVEY
DN2580.in October 2023.
DN2580
DN2580.Significant digits in the geoid height do not necessarily reflect accuracy.
DN2580.GEOID18 height accuracy estimate available here.

DN2580.The PID for the CORS L1 Phase Center is DR6186.

DN2580.Click photographs - Photos may exist for this station.
DN2580
DN2580.The XYZ, and position/ellipsoidal ht. are equivalent.
DN2580
DN2580.The ellipsoidal height was determined by GPS observations
DN2580.and is referenced to NAD 83.
