DN4510.The coordinates were established by GPS observations
DN4510.and adjusted by the National Geodetic Survey in April 2022.
DN4510
DN4510.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN4510.been affixed to the stable North American Tectonic Plate.
DN4510
DN4510.The coordinates are valid at the epoch date displayed above
DN4510.which is a decimal equivalence of Year/Month/Day.
DN4510
DN4510.Due to the release of the International GNSS Service (IGS) 2014
DN4510.realization of the International Terrestrial Reference Frame of 2014
DN4510.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN4510.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN4510.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN4510.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN4510.currently published epoch of 2010.00.
DN4510
DN4510.Additional information on MYCS2 is available at
DN4510.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN4510.Significant digits in the geoid height do not necessarily reflect accuracy.
DN4510.GEOID18 height accuracy estimate available here.

DN4510.Click photographs - Photos may exist for this station.
DN4510
DN4510.The XYZ, and position/ellipsoidal ht. are equivalent.
DN4510
DN4510.The ellipsoidal height was determined by GPS observations
DN4510.and is referenced to NAD 83.
