DO8861.The coordinates were established by GPS observations
DO8861.and adjusted by the National Geodetic Survey in April 2022.
DO8861
DO8861.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO8861.been affixed to the stable North American Tectonic Plate.
DO8861
DO8861.The coordinates are valid at the epoch date displayed above
DO8861.which is a decimal equivalence of Year/Month/Day.
DO8861
DO8861.Due to the release of the International GNSS Service (IGS) 2014
DO8861.realization of the International Terrestrial Reference Frame of 2014
DO8861.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO8861.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO8861.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO8861.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO8861.currently published epoch of 2010.00.
DO8861
DO8861.Additional information on MYCS2 is available at
DO8861.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO8861.Significant digits in the geoid height do not necessarily reflect accuracy.
DO8861.GEOID18 height accuracy estimate available here.

DO8861.The XYZ, and position/ellipsoidal ht. are equivalent.
DO8861
DO8861.The ellipsoidal height was determined by GPS observations
DO8861.and is referenced to NAD 83.
