DO4955.The coordinates were established by GPS observations
DO4955.and adjusted by the National Geodetic Survey in June 2019.
DO4955
DO4955.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO4955.been affixed to the stable North American Tectonic Plate.
DO4955
DO4955.The coordinates are valid at the epoch date displayed above
DO4955.which is a decimal equivalence of Year/Month/Day.
DO4955
DO4955.Due to the release of the International GNSS Service (IGS) 2014
DO4955.realization of the International Terrestrial Reference Frame of 2014
DO4955.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO4955.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO4955.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO4955.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO4955.currently published epoch of 2010.00.
DO4955
DO4955.Additional information on MYCS2 is available at
DO4955.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO4955.The XYZ, and position/ellipsoidal ht. are equivalent.
DO4955
DO4955.The ellipsoidal height was determined by GPS observations
DO4955.and is referenced to NAD 83.
