DK4107.The coordinates were established by GPS observations
DK4107.and adjusted by the National Geodetic Survey in May 2021.
DK4107
DK4107.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK4107.been affixed to the stable North American Tectonic Plate.
DK4107
DK4107.The coordinates are valid at the epoch date displayed above
DK4107.which is a decimal equivalence of Year/Month/Day.
DK4107
DK4107.Due to the release of the International GNSS Service (IGS) 2014
DK4107.realization of the International Terrestrial Reference Frame of 2014
DK4107.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK4107.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK4107.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK4107.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK4107.currently published epoch of 2010.00.
DK4107
DK4107.Additional information on MYCS2 is available at
DK4107.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK4107
DK4107.The orthometric height was determined by GPS observations and a
DK4107.high-resolution geoid model using precise GPS observation and
DK4107.processing techniques.
DK4107
DK4107.Significant digits in the geoid height do not necessarily reflect accuracy.
DK4107.GEOID18 height accuracy estimate available here.
DK4107
DK4107.The PID for the CORS L1 Phase Center is DR8293.

DK4107.Click photographs - Photos may exist for this station.
DK4107
DK4107.The XYZ, and position/ellipsoidal ht. are equivalent.
DK4107
DK4107.The ellipsoidal height was determined by GPS observations
DK4107.and is referenced to NAD 83.
