DO6442.The coordinates were established by GPS observations
DO6442.and adjusted by the National Geodetic Survey in May 2020.
DO6442
DO6442.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO6442.been affixed to the stable North American Tectonic Plate.
DO6442
DO6442.The coordinates are valid at the epoch date displayed above
DO6442.which is a decimal equivalence of Year/Month/Day.
DO6442
DO6442.Due to the release of the International GNSS Service (IGS) 2014
DO6442.realization of the International Terrestrial Reference Frame of 2014
DO6442.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO6442.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO6442.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO6442.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO6442.currently published epoch of 2010.00.
DO6442
DO6442.Additional information on MYCS2 is available at

DO6442.Significant digits in the geoid height do not necessarily reflect accuracy.
DO6442.GEOID18 height accuracy estimate available here.

DO6442.The XYZ, and position/ellipsoidal ht. are equivalent.
DO6442
DO6442.The ellipsoidal height was determined by GPS observations
DO6442.and is referenced to NAD 83.
