DN9087.The coordinates were established by GPS observations
DN9087.and adjusted by the National Geodetic Survey in May 2021.
DN9087
DN9087.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN9087.been affixed to the stable North American Tectonic Plate.
DN9087
DN9087.The coordinates are valid at the epoch date displayed above
DN9087.which is a decimal equivalence of Year/Month/Day.
DN9087
DN9087.Due to the release of the International GNSS Service (IGS) 2014
DN9087.realization of the International Terrestrial Reference Frame of 2014
DN9087.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN9087.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN9087.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN9087.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN9087.currently published epoch of 2010.00.
DN9087
DN9087.Additional information on MYCS2 is available at
DN9087.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN9087.Significant digits in the geoid height do not necessarily reflect accuracy.
DN9087.GEOID18 height accuracy estimate available here.

DN9087.Click photographs - Photos may exist for this station.
DN9087
DN9087.The XYZ, and position/ellipsoidal ht. are equivalent.
DN9087
DN9087.The ellipsoidal height was determined by GPS observations
DN9087.and is referenced to NAD 83.
