DG8521.The coordinates were established by GPS observations
DG8521.and adjusted by the National Geodetic Survey in June 2019.
DG8521
DG8521.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG8521.been affixed to the stable North American Tectonic Plate.
DG8521
DG8521.The coordinates are valid at the epoch date displayed above
DG8521.which is a decimal equivalence of Year/Month/Day.
DG8521
DG8521.Due to the release of the International GNSS Service (IGS) 2014
DG8521.realization of the International Terrestrial Reference Frame of 2014
DG8521.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG8521.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG8521.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG8521.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG8521.currently published epoch of 2010.00.
DG8521
DG8521.Additional information on MYCS2 is available at
DG8521.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG8521
DG8521.The orthometric height was determined by GPS observations and a
DG8521.high-resolution geoid model using precise GPS observation and
DG8521.processing techniques.
DG8521
DG8521.Significant digits in the geoid height do not necessarily reflect accuracy.
DG8521.GEOID18 height accuracy estimate available here.
DG8521
DG8521.The PID for the CORS L1 Phase Center is DR7668.

DG8521.Click photographs - Photos may exist for this station.
DG8521
DG8521.The XYZ, and position/ellipsoidal ht. are equivalent.
DG8521
DG8521.The ellipsoidal height was determined by GPS observations
DG8521.and is referenced to NAD 83.
