DG9659.The coordinates were established by GPS observations
DG9659.and adjusted by the National Geodetic Survey in June 2019.
DG9659
DG9659.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9659.been affixed to the stable North American Tectonic Plate.
DG9659
DG9659.The coordinates are valid at the epoch date displayed above
DG9659.which is a decimal equivalence of Year/Month/Day.
DG9659
DG9659.Due to the release of the International GNSS Service (IGS) 2014
DG9659.realization of the International Terrestrial Reference Frame of 2014
DG9659.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9659.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9659.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9659.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9659.currently published epoch of 2010.00.
DG9659
DG9659.Additional information on MYCS2 is available at
DG9659.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG9659
DG9659.The orthometric height was determined by GPS observations and a
DG9659.high-resolution geoid model using precise GPS observation and
DG9659.processing techniques.
DG9659
DG9659.Significant digits in the geoid height do not necessarily reflect accuracy.
DG9659.GEOID18 height accuracy estimate available here.
DG9659
DG9659.The PID for the CORS L1 Phase Center is DG9660.

DG9659.Click photographs - Photos may exist for this station.
DG9659
DG9659.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9659
DG9659.The ellipsoidal height was determined by GPS observations
DG9659.and is referenced to NAD 83.
