DN8743.The coordinates were established by GPS observations
DN8743.and adjusted by the National Geodetic Survey in June 2019.
DN8743
DN8743.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN8743.been affixed to the stable North American Tectonic Plate.
DN8743
DN8743.The coordinates are valid at the epoch date displayed above
DN8743.which is a decimal equivalence of Year/Month/Day.
DN8743
DN8743.Due to the release of the International GNSS Service (IGS) 2014
DN8743.realization of the International Terrestrial Reference Frame of 2014
DN8743.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN8743.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN8743.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN8743.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN8743.currently published epoch of 2010.00.
DN8743
DN8743.Additional information on MYCS2 is available at
DN8743.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DN8743
DN8743.The orthometric height was determined by GPS observations and a
DN8743.high-resolution geoid model using precise GPS observation and
DN8743.processing techniques.
DN8743
DN8743.Significant digits in the geoid height do not necessarily reflect accuracy.
DN8743.GEOID18 height accuracy estimate available here.
DN8743
DN8743.The PID for the CORS L1 Phase Center is DN8744.

DN8743.Click photographs - Photos may exist for this station.
DN8743
DN8743.The XYZ, and position/ellipsoidal ht. are equivalent.
DN8743
DN8743.The ellipsoidal height was determined by GPS observations
DN8743.and is referenced to NAD 83.
