DF8462.The coordinates were established by GPS observations
DF8462.and adjusted by the National Geodetic Survey in June 2019.
DF8462
DF8462.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF8462.been affixed to the stable North American Tectonic Plate.
DF8462
DF8462.The coordinates are valid at the epoch date displayed above
DF8462.which is a decimal equivalence of Year/Month/Day.
DF8462
DF8462.Due to the release of the International GNSS Service (IGS) 2014
DF8462.realization of the International Terrestrial Reference Frame of 2014
DF8462.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF8462.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF8462.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF8462.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF8462.currently published epoch of 2010.00.
DF8462
DF8462.Additional information on MYCS2 is available at
DF8462.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF8462
DF8462.The orthometric height was determined by differential leveling and
DF8462.adjusted by the NATIONAL GEODETIC SURVEY
DF8462.in May 2008.
DF8462
DF8462.No vertical observational check was made to the station.
DF8462
DF8462.Significant digits in the geoid height do not necessarily reflect accuracy.
DF8462.GEOID18 height accuracy estimate available here.
DF8462
DF8462.The PID for the CORS L1 Phase Center is DG4815.

DF8462.Click photographs - Photos may exist for this station.
DF8462
DF8462.The XYZ, and position/ellipsoidal ht. are equivalent.
DF8462
DF8462.The ellipsoidal height was determined by GPS observations
DF8462.and is referenced to NAD 83.
