DO1797.The coordinates were established by GPS observations
DO1797.and adjusted by the National Geodetic Survey in July 2022.
DO1797
DO1797.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO1797.been affixed to the stable North American Tectonic Plate.
DO1797
DO1797.The coordinates are valid at the epoch date displayed above
DO1797.which is a decimal equivalence of Year/Month/Day.
DO1797
DO1797.Due to the release of the International GNSS Service (IGS) 2014
DO1797.realization of the International Terrestrial Reference Frame of 2014
DO1797.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO1797.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO1797.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO1797.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO1797.currently published epoch of 2010.00.
DO1797
DO1797.Additional information on MYCS2 is available at

DO1797
DO1797.The ellipsoidal height was determined by GPS observations
DO1797.and is referenced to NAD 83.
