DJ8885.The coordinates were established by GPS observations
DJ8885.and adjusted by the National Geodetic Survey in June 2019.
DJ8885
DJ8885.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DJ8885.been affixed to the stable North American Tectonic Plate.
DJ8885
DJ8885.The coordinates are valid at the epoch date displayed above
DJ8885.which is a decimal equivalence of Year/Month/Day.
DJ8885
DJ8885.Due to the release of the International GNSS Service (IGS) 2014
DJ8885.realization of the International Terrestrial Reference Frame of 2014
DJ8885.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DJ8885.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DJ8885.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DJ8885.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DJ8885.currently published epoch of 2010.00.
DJ8885
DJ8885.Additional information on MYCS2 is available at
DJ8885.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DJ8885
DJ8885.The orthometric height was determined by GPS observations and a
DJ8885.high-resolution geoid model using precise GPS observation and
DJ8885.processing techniques.
DJ8885
DJ8885.Significant digits in the geoid height do not necessarily reflect accuracy.
DJ8885.GEOID18 height accuracy estimate available here.
DJ8885
DJ8885.The PID for the CORS L1 Phase Center is DL6834.

DJ8885
DJ8885.The XYZ, and position/ellipsoidal ht. are equivalent.
DJ8885
DJ8885.The ellipsoidal height was determined by GPS observations
DJ8885.and is referenced to NAD 83.
