DN7479.The coordinates were established by GPS observations
DN7479.and adjusted by the National Geodetic Survey in June 2019.
DN7479
DN7479.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN7479.been affixed to the stable North American Tectonic Plate.
DN7479
DN7479.The coordinates are valid at the epoch date displayed above
DN7479.which is a decimal equivalence of Year/Month/Day.
DN7479
DN7479.Due to the release of the International GNSS Service (IGS) 2014
DN7479.realization of the International Terrestrial Reference Frame of 2014
DN7479.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN7479.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN7479.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN7479.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN7479.currently published epoch of 2010.00.
DN7479
DN7479.Additional information on MYCS2 is available at
DN7479.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN7479.Significant digits in the geoid height do not necessarily reflect accuracy.
DN7479.GEOID18 height accuracy estimate available here.

DN7479.Click photographs - Photos may exist for this station.
DN7479
DN7479.The XYZ, and position/ellipsoidal ht. are equivalent.
DN7479
DN7479.The ellipsoidal height was determined by GPS observations
DN7479.and is referenced to NAD 83.
