DG4689.The coordinates were established by GPS observations
DG4689.and adjusted by the National Geodetic Survey in June 2019.
DG4689
DG4689.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DG4689.been affixed to the stable North American Tectonic Plate.
DG4689
DG4689.The coordinates are valid at the epoch date displayed above
DG4689.which is a decimal equivalence of Year/Month/Day.
DG4689
DG4689.Due to the release of the International GNSS Service (IGS) 2014
DG4689.realization of the International Terrestrial Reference Frame of 2014
DG4689.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DG4689.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DG4689.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DG4689.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DG4689.currently published epoch of 2010.00.
DG4689
DG4689.Additional information on MYCS2 is available at
DG4689.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DG4689
DG4689.The orthometric height was determined by differential leveling and
DG4689.adjusted by the NATIONAL GEODETIC SURVEY
DG4689.in April 2010.
DG4689
DG4689.No vertical observational check was made to the station.
DG4689
DG4689.Significant digits in the geoid height do not necessarily reflect accuracy.
DG4689.GEOID18 height accuracy estimate available here.
DG4689
DG4689.The PID for the CORS L1 Phase Center is DR1470.

DG4689.Click photographs - Photos may exist for this station.
DG4689
DG4689.The XYZ, and position/ellipsoidal ht. are equivalent.
DG4689
DG4689.The ellipsoidal height was determined by GPS observations
DG4689.and is referenced to NAD 83.
