DM5373.The coordinates were established by GPS observations
DM5373.and adjusted by the National Geodetic Survey in June 2019.
DM5373
DM5373.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM5373.been affixed to the stable North American Tectonic Plate.
DM5373
DM5373.The coordinates are valid at the epoch date displayed above
DM5373.which is a decimal equivalence of Year/Month/Day.
DM5373
DM5373.Due to the release of the International GNSS Service (IGS) 2014
DM5373.realization of the International Terrestrial Reference Frame of 2014
DM5373.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM5373.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM5373.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM5373.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM5373.currently published epoch of 2010.00.
DM5373
DM5373.Additional information on MYCS2 is available at
DM5373.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM5373
DM5373.The orthometric height was determined by differential leveling and
DM5373.adjusted by the NATIONAL GEODETIC SURVEY
DM5373.in December 2011.
DM5373
DM5373.No vertical observational check was made to the station.
DM5373
DM5373.Significant digits in the geoid height do not necessarily reflect accuracy.
DM5373.GEOID18 height accuracy estimate available here.
DM5373
DM5373.The PID for the CORS L1 Phase Center is DM5374.

DM5373.Click photographs - Photos may exist for this station.
DM5373
DM5373.The XYZ, and position/ellipsoidal ht. are equivalent.
DM5373
DM5373.The ellipsoidal height was determined by GPS observations
DM5373.and is referenced to NAD 83.
