DN4508.The coordinates were established by GPS observations
DN4508.and adjusted by the National Geodetic Survey in April 2022.
DN4508
DN4508.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN4508.been affixed to the stable North American Tectonic Plate.
DN4508
DN4508.The coordinates are valid at the epoch date displayed above
DN4508.which is a decimal equivalence of Year/Month/Day.
DN4508
DN4508.Due to the release of the International GNSS Service (IGS) 2014
DN4508.realization of the International Terrestrial Reference Frame of 2014
DN4508.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN4508.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN4508.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN4508.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN4508.currently published epoch of 2010.00.
DN4508
DN4508.Additional information on MYCS2 is available at
DN4508.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN4508.Significant digits in the geoid height do not necessarily reflect accuracy.
DN4508.GEOID18 height accuracy estimate available here.

DN4508.The XYZ, and position/ellipsoidal ht. are equivalent.
DN4508
DN4508.The ellipsoidal height was determined by GPS observations
DN4508.and is referenced to NAD 83.
