DO1821.The coordinates were established by GPS observations
DO1821.and adjusted by the National Geodetic Survey in June 2019.
DO1821
DO1821.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO1821.been affixed to the stable North American Tectonic Plate.
DO1821
DO1821.The coordinates are valid at the epoch date displayed above
DO1821.which is a decimal equivalence of Year/Month/Day.
DO1821
DO1821.Due to the release of the International GNSS Service (IGS) 2014
DO1821.realization of the International Terrestrial Reference Frame of 2014
DO1821.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO1821.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO1821.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO1821.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO1821.currently published epoch of 2010.00.
DO1821
DO1821.Additional information on MYCS2 is available at
DO1821.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO1821.Click photographs - Photos may exist for this station.
DO1821
DO1821.The XYZ, and position/ellipsoidal ht. are equivalent.
DO1821
DO1821.The ellipsoidal height was determined by GPS observations
DO1821.and is referenced to NAD 83.
