DN7527.The coordinates were established by GPS observations
DN7527.and adjusted by the National Geodetic Survey in June 2019.
DN7527
DN7527.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN7527.been affixed to the stable North American Tectonic Plate.
DN7527
DN7527.The coordinates are valid at the epoch date displayed above
DN7527.which is a decimal equivalence of Year/Month/Day.
DN7527
DN7527.Due to the release of the International GNSS Service (IGS) 2014
DN7527.realization of the International Terrestrial Reference Frame of 2014
DN7527.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN7527.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN7527.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN7527.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN7527.currently published epoch of 2010.00.
DN7527
DN7527.Additional information on MYCS2 is available at
DN7527.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN7527.Significant digits in the geoid height do not necessarily reflect accuracy.
DN7527.GEOID18 height accuracy estimate available here.

DN7527.The PID for the CORS L1 Phase Center is DR3598.

DN7527
DN7527.The XYZ, and position/ellipsoidal ht. are equivalent.
DN7527
DN7527.The ellipsoidal height was determined by GPS observations
DN7527.and is referenced to NAD 83.
