DO8879.The coordinates were established by GPS observations
DO8879.and adjusted by the National Geodetic Survey in December 2022.
DO8879
DO8879.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO8879.been affixed to the stable North American Tectonic Plate.
DO8879
DO8879.The coordinates are valid at the epoch date displayed above
DO8879.which is a decimal equivalence of Year/Month/Day.
DO8879
DO8879.Due to the release of the International GNSS Service (IGS) 2014
DO8879.realization of the International Terrestrial Reference Frame of 2014
DO8879.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO8879.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO8879.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO8879.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO8879.currently published epoch of 2010.00.
DO8879
DO8879.Additional information on MYCS2 is available at

DO8879.Significant digits in the geoid height do not necessarily reflect accuracy.
DO8879.GEOID18 height accuracy estimate available here.

DO8879.The XYZ, and position/ellipsoidal ht. are equivalent.
DO8879
DO8879.The ellipsoidal height was determined by GPS observations
DO8879.and is referenced to NAD 83.
