DK7845.The coordinates were established by GPS observations
DK7845.and adjusted by the National Geodetic Survey in June 2019.
DK7845
DK7845.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK7845.been affixed to the stable North American Tectonic Plate.
DK7845
DK7845.The coordinates are valid at the epoch date displayed above
DK7845.which is a decimal equivalence of Year/Month/Day.
DK7845
DK7845.Due to the release of the International GNSS Service (IGS) 2014
DK7845.realization of the International Terrestrial Reference Frame of 2014
DK7845.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK7845.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK7845.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK7845.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK7845.currently published epoch of 2010.00.
DK7845
DK7845.Additional information on MYCS2 is available at
DK7845.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK7845
DK7845.The orthometric height was determined by GPS observations and a
DK7845.high-resolution geoid model using precise GPS observation and
DK7845.processing techniques.
DK7845
DK7845.Significant digits in the geoid height do not necessarily reflect accuracy.
DK7845.GEOID18 height accuracy estimate available here.
DK7845
DK7845.The PID for the CORS L1 Phase Center is DR5978.

DK7845.Click photographs - Photos may exist for this station.
DK7845
DK7845.The XYZ, and position/ellipsoidal ht. are equivalent.
DK7845
DK7845.The ellipsoidal height was determined by GPS observations
DK7845.and is referenced to NAD 83.
