DO1812.The coordinates were established by GPS observations
DO1812.and adjusted by the National Geodetic Survey in January 2023.
DO1812
DO1812.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO1812.been affixed to the stable North American Tectonic Plate.
DO1812
DO1812.The coordinates are valid at the epoch date displayed above
DO1812.which is a decimal equivalence of Year/Month/Day.
DO1812
DO1812.Due to the release of the International GNSS Service (IGS) 2014
DO1812.realization of the International Terrestrial Reference Frame of 2014
DO1812.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO1812.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO1812.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO1812.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO1812.currently published epoch of 2010.00.
DO1812
DO1812.Additional information on MYCS2 is available at
DO1812.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO1812.The XYZ, and position/ellipsoidal ht. are equivalent.
DO1812
DO1812.The ellipsoidal height was determined by GPS observations
DO1812.and is referenced to NAD 83.
