DG9806.The coordinates were established by GPS observations
DG9806.and adjusted by the National Geodetic Survey in June 2019.
DG9806
DG9806.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG9806.been affixed to the stable North American Tectonic Plate.
DG9806
DG9806.The coordinates are valid at the epoch date displayed above
DG9806.which is a decimal equivalence of Year/Month/Day.
DG9806
DG9806.Due to the release of the International GNSS Service (IGS) 2014
DG9806.realization of the International Terrestrial Reference Frame of 2014
DG9806.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG9806.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG9806.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG9806.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG9806.currently published epoch of 2010.00.
DG9806
DG9806.Additional information on MYCS2 is available at
DG9806.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG9806
DG9806.The orthometric height was determined by GPS observations and a
DG9806.high-resolution geoid model using precise GPS observation and
DG9806.processing techniques.
DG9806
DG9806.Significant digits in the geoid height do not necessarily reflect accuracy.
DG9806.GEOID18 height accuracy estimate available here.
DG9806
DG9806.The PID for the CORS L1 Phase Center is DR7672.

DG9806.The XYZ, and position/ellipsoidal ht. are equivalent.
DG9806
DG9806.The ellipsoidal height was determined by GPS observations
DG9806.and is referenced to NAD 83.
