DN7461.The coordinates were established by GPS observations
DN7461.and adjusted by the National Geodetic Survey in June 2019.
DN7461
DN7461.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN7461.been affixed to the stable North American Tectonic Plate.
DN7461
DN7461.The coordinates are valid at the epoch date displayed above
DN7461.which is a decimal equivalence of Year/Month/Day.
DN7461
DN7461.Due to the release of the International GNSS Service (IGS) 2014
DN7461.realization of the International Terrestrial Reference Frame of 2014
DN7461.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN7461.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN7461.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN7461.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN7461.currently published epoch of 2010.00.
DN7461
DN7461.Additional information on MYCS2 is available at
DN7461.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN7461.Significant digits in the geoid height do not necessarily reflect accuracy.
DN7461.GEOID18 height accuracy estimate available here.

DN7461.The XYZ, and position/ellipsoidal ht. are equivalent.
DN7461
DN7461.The ellipsoidal height was determined by GPS observations
DN7461.and is referenced to NAD 83.
