DO2381.The coordinates were established by GPS observations
DO2381.and adjusted by the National Geodetic Survey in June 2019.
DO2381
DO2381.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO2381.been affixed to the stable North American Tectonic Plate.
DO2381
DO2381.The coordinates are valid at the epoch date displayed above
DO2381.which is a decimal equivalence of Year/Month/Day.
DO2381
DO2381.Due to the release of the International GNSS Service (IGS) 2014
DO2381.realization of the International Terrestrial Reference Frame of 2014
DO2381.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO2381.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO2381.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO2381.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO2381.currently published epoch of 2010.00.
DO2381
DO2381.Additional information on MYCS2 is available at
DO2381.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO2381.Click photographs - Photos may exist for this station.
DO2381
DO2381.The XYZ, and position/ellipsoidal ht. are equivalent.
DO2381
DO2381.The ellipsoidal height was determined by GPS observations
DO2381.and is referenced to NAD 83.
