DG9787.The coordinates were established by GPS observations
DG9787.and adjusted by the National Geodetic Survey in July 2020.
DG9787
DG9787.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9787.been affixed to the stable North American Tectonic Plate.
DG9787
DG9787.The coordinates are valid at the epoch date displayed above
DG9787.which is a decimal equivalence of Year/Month/Day.
DG9787
DG9787.Due to the release of the International GNSS Service (IGS) 2014
DG9787.realization of the International Terrestrial Reference Frame of 2014
DG9787.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9787.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9787.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9787.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9787.currently published epoch of 2010.00.
DG9787
DG9787.Additional information on MYCS2 is available at
DG9787.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG9787
DG9787.The orthometric height was determined by GPS observations and a
DG9787.high-resolution geoid model using precise GPS observation and
DG9787.processing techniques.
DG9787
DG9787.Significant digits in the geoid height do not necessarily reflect accuracy.
DG9787.GEOID18 height accuracy estimate available here.
DG9787
DG9787.The PID for the CORS L1 Phase Center is DR5940.

DG9787.Click photographs - Photos may exist for this station.
DG9787
DG9787.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9787
DG9787.The ellipsoidal height was determined by GPS observations
DG9787.and is referenced to NAD 83.
