DO9473.The coordinates were established by GPS observations
DO9473.and adjusted by the National Geodetic Survey in May 2020.
DO9473
DO9473.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO9473.been affixed to the stable North American Tectonic Plate.
DO9473
DO9473.The coordinates are valid at the epoch date displayed above
DO9473.which is a decimal equivalence of Year/Month/Day.
DO9473
DO9473.Due to the release of the International GNSS Service (IGS) 2014
DO9473.realization of the International Terrestrial Reference Frame of 2014
DO9473.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO9473.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO9473.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO9473.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO9473.currently published epoch of 2010.00.
DO9473
DO9473.Additional information on MYCS2 is available at
DO9473.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO9473.Significant digits in the geoid height do not necessarily reflect accuracy.
DO9473.GEOID18 height accuracy estimate available here.

DO9473.Click photographs - Photos may exist for this station.
DO9473
DO9473.The XYZ, and position/ellipsoidal ht. are equivalent.
DO9473
DO9473.The ellipsoidal height was determined by GPS observations
DO9473.and is referenced to NAD 83.
