DO9480.The coordinates were established by GPS observations
DO9480.and adjusted by the National Geodetic Survey in June 2019.
DO9480
DO9480.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO9480.been affixed to the stable North American Tectonic Plate.
DO9480
DO9480.The coordinates are valid at the epoch date displayed above
DO9480.which is a decimal equivalence of Year/Month/Day.
DO9480
DO9480.Due to the release of the International GNSS Service (IGS) 2014
DO9480.realization of the International Terrestrial Reference Frame of 2014
DO9480.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO9480.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO9480.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO9480.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO9480.currently published epoch of 2010.00.
DO9480
DO9480.Additional information on MYCS2 is available at
DO9480.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO9480.Significant digits in the geoid height do not necessarily reflect accuracy.

DO9480.Click photographs - Photos may exist for this station.
DO9480
DO9480.The XYZ, and position/ellipsoidal ht. are equivalent.
DO9480
DO9480.The ellipsoidal height was determined by GPS observations
DO9480.and is referenced to NAD 83.
