DJ8957.The coordinates were established by GPS observations
DJ8957.and adjusted by the National Geodetic Survey in June 2019.
DJ8957
DJ8957.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DJ8957.been affixed to the stable North American Tectonic Plate.
DJ8957
DJ8957.The coordinates are valid at the epoch date displayed above
DJ8957.which is a decimal equivalence of Year/Month/Day.
DJ8957
DJ8957.Due to the release of the International GNSS Service (IGS) 2014
DJ8957.realization of the International Terrestrial Reference Frame of 2014
DJ8957.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DJ8957.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DJ8957.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DJ8957.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DJ8957.currently published epoch of 2010.00.
DJ8957
DJ8957.Additional information on MYCS2 is available at
DJ8957.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DJ8957
DJ8957.The orthometric height was determined by GPS observations and a
DJ8957.high-resolution geoid model using precise GPS observation and
DJ8957.processing techniques.
DJ8957
DJ8957.Significant digits in the geoid height do not necessarily reflect accuracy.
DJ8957.GEOID18 height accuracy estimate available here.
DJ8957
DJ8957.The PID for the CORS L1 Phase Center is DR7732.

DJ8957
DJ8957.The XYZ, and position/ellipsoidal ht. are equivalent.
DJ8957
DJ8957.The ellipsoidal height was determined by GPS observations
DJ8957.and is referenced to NAD 83.
DJ8957
DJ8957. The following values were computed from the NAD 83(2011) position.
