DG9800.The coordinates were established by GPS observations
DG9800.and adjusted by the National Geodetic Survey in May 2021.
DG9800
DG9800.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9800.been affixed to the stable North American Tectonic Plate.
DG9800
DG9800.The coordinates are valid at the epoch date displayed above
DG9800.which is a decimal equivalence of Year/Month/Day.
DG9800
DG9800.Due to the release of the International GNSS Service (IGS) 2014
DG9800.realization of the International Terrestrial Reference Frame of 2014
DG9800.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9800.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9800.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9800.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9800.currently published epoch of 2010.00.
DG9800
DG9800.Additional information on MYCS2 is available at
DG9800.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG9800
DG9800.The orthometric height was determined by GPS observations and a
DG9800.high-resolution geoid model using precise GPS observation and
DG9800.processing techniques.
DG9800
DG9800.Significant digits in the geoid height do not necessarily reflect accuracy.
DG9800.GEOID18 height accuracy estimate available here.
DG9800
DG9800.The PID for the CORS L1 Phase Center is DR9269.

DG9800.Click photographs - Photos may exist for this station.
DG9800
DG9800.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9800
DG9800.The ellipsoidal height was determined by GPS observations
DG9800.and is referenced to NAD 83.
