DO8873.The coordinates were established by GPS observations
DO8873.and adjusted by the National Geodetic Survey in March 2022.
DO8873
DO8873.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO8873.been affixed to the stable North American Tectonic Plate.
DO8873
DO8873.The coordinates are valid at the epoch date displayed above
DO8873.which is a decimal equivalence of Year/Month/Day.
DO8873
DO8873.Due to the release of the International GNSS Service (IGS) 2014
DO8873.realization of the International Terrestrial Reference Frame of 2014
DO8873.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO8873.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO8873.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO8873.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO8873.currently published epoch of 2010.00.
DO8873
DO8873.Additional information on MYCS2 is available at
DO8873.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO8873.Significant digits in the geoid height do not necessarily reflect accuracy.
DO8873.GEOID18 height accuracy estimate available here.

DO8873.The XYZ, and position/ellipsoidal ht. are equivalent.
DO8873
DO8873.The ellipsoidal height was determined by GPS observations
DO8873.and is referenced to NAD 83.
