DG9747.The coordinates were established by GPS observations
DG9747.and adjusted by the National Geodetic Survey in June 2019.
DG9747
DG9747.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9747.been affixed to the stable North American Tectonic Plate.
DG9747
DG9747.The coordinates are valid at the epoch date displayed above
DG9747.which is a decimal equivalence of Year/Month/Day.
DG9747
DG9747.Due to the release of the International GNSS Service (IGS) 2014
DG9747.realization of the International Terrestrial Reference Frame of 2014
DG9747.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9747.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9747.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9747.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9747.currently published epoch of 2010.00.
DG9747
DG9747.Additional information on MYCS2 is available at
DG9747.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG9747
DG9747.The orthometric height was determined by GPS observations and a
DG9747.high-resolution geoid model using precise GPS observation and
DG9747.processing techniques.
DG9747
DG9747.Significant digits in the geoid height do not necessarily reflect accuracy.
DG9747.GEOID18 height accuracy estimate available here.
DG9747
DG9747.The PID for the CORS L1 Phase Center is DR6163.

DG9747.Click photographs - Photos may exist for this station.
DG9747
DG9747.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9747
DG9747.The ellipsoidal height was determined by GPS observations
DG9747.and is referenced to NAD 83.
