DK8257.The coordinates were established by GPS observations
DK8257.and adjusted by the National Geodetic Survey in June 2019.
DK8257
DK8257.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK8257.been affixed to the stable North American Tectonic Plate.
DK8257
DK8257.The coordinates are valid at the epoch date displayed above
DK8257.which is a decimal equivalence of Year/Month/Day.
DK8257
DK8257.Due to the release of the International GNSS Service (IGS) 2014
DK8257.realization of the International Terrestrial Reference Frame of 2014
DK8257.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK8257.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK8257.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK8257.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK8257.currently published epoch of 2010.00.
DK8257
DK8257.Additional information on MYCS2 is available at
DK8257.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK8257
DK8257.The orthometric height was determined by GPS observations and a
DK8257.high-resolution geoid model using precise GPS observation and
DK8257.processing techniques.
DK8257
DK8257.Significant digits in the geoid height do not necessarily reflect accuracy.
DK8257.GEOID18 height accuracy estimate available here.
DK8257
DK8257.The PID for the CORS L1 Phase Center is DK8258.

DK8257.Click photographs - Photos may exist for this station.
DK8257
DK8257.The XYZ, and position/ellipsoidal ht. are equivalent.
DK8257
DK8257.The ellipsoidal height was determined by GPS observations
DK8257.and is referenced to NAD 83.
