DK7414.The coordinates were established by GPS observations
DK7414.and adjusted by the National Geodetic Survey in June 2019.
DK7414
DK7414.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK7414.been affixed to the stable North American Tectonic Plate.
DK7414
DK7414.The coordinates are valid at the epoch date displayed above
DK7414.which is a decimal equivalence of Year/Month/Day.
DK7414
DK7414.Due to the release of the International GNSS Service (IGS) 2014
DK7414.realization of the International Terrestrial Reference Frame of 2014
DK7414.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK7414.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK7414.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK7414.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK7414.currently published epoch of 2010.00.
DK7414
DK7414.Additional information on MYCS2 is available at
DK7414.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DK7414
DK7414.The orthometric height was determined by GPS observations and a
DK7414.high-resolution geoid model using precise GPS observation and
DK7414.processing techniques.
DK7414
DK7414.Significant digits in the geoid height do not necessarily reflect accuracy.
DK7414.GEOID18 height accuracy estimate available here.
DK7414
DK7414.The PID for the CORS L1 Phase Center is DN6723.

DK7414.Click photographs - Photos may exist for this station.
DK7414
DK7414.The XYZ, and position/ellipsoidal ht. are equivalent.
DK7414
DK7414.The ellipsoidal height was determined by GPS observations
DK7414.and is referenced to NAD 83.
