DN9938.The coordinates were established by GPS observations
DN9938.and adjusted by the National Geodetic Survey in June 2022.
DN9938
DN9938.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN9938.been affixed to the stable North American Tectonic Plate.
DN9938
DN9938.The coordinates are valid at the epoch date displayed above
DN9938.which is a decimal equivalence of Year/Month/Day.
DN9938
DN9938.Due to the release of the International GNSS Service (IGS) 2014
DN9938.realization of the International Terrestrial Reference Frame of 2014
DN9938.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN9938.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN9938.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN9938.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN9938.currently published epoch of 2010.00.
DN9938
DN9938.Additional information on MYCS2 is available at
DN9938.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN9938.Significant digits in the geoid height do not necessarily reflect accuracy.
DN9938.GEOID18 height accuracy estimate available here.

DN9938.Click photographs - Photos may exist for this station.
DN9938
DN9938.The XYZ, and position/ellipsoidal ht. are equivalent.
DN9938
DN9938.The ellipsoidal height was determined by GPS observations
DN9938.and is referenced to NAD 83.
