DN7458.The coordinates were established by GPS observations
DN7458.and adjusted by the National Geodetic Survey in June 2019.
DN7458
DN7458.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN7458.been affixed to the stable North American Tectonic Plate.
DN7458
DN7458.The coordinates are valid at the epoch date displayed above
DN7458.which is a decimal equivalence of Year/Month/Day.
DN7458
DN7458.Due to the release of the International GNSS Service (IGS) 2014
DN7458.realization of the International Terrestrial Reference Frame of 2014
DN7458.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN7458.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN7458.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN7458.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN7458.currently published epoch of 2010.00.
DN7458
DN7458.Additional information on MYCS2 is available at
DN7458.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN7458.Significant digits in the geoid height do not necessarily reflect accuracy.
DN7458.GEOID18 height accuracy estimate available here.

DN7458.The XYZ, and position/ellipsoidal ht. are equivalent.
DN7458
DN7458.The ellipsoidal height was determined by GPS observations
DN7458.and is referenced to NAD 83.
