DJ8953.The coordinates were established by GPS observations
DJ8953.and adjusted by the National Geodetic Survey in December 2022.
DJ8953
DJ8953.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DJ8953.been affixed to the stable North American Tectonic Plate.
DJ8953
DJ8953.The coordinates are valid at the epoch date displayed above
DJ8953.which is a decimal equivalence of Year/Month/Day.
DJ8953
DJ8953.Due to the release of the International GNSS Service (IGS) 2014
DJ8953.realization of the International Terrestrial Reference Frame of 2014
DJ8953.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DJ8953.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DJ8953.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DJ8953.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DJ8953.currently published epoch of 2010.00.
DJ8953
DJ8953.Additional information on MYCS2 is available at
DJ8953.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DJ8953.Significant digits in the geoid height do not necessarily reflect accuracy.

DJ8953.The XYZ, and position/ellipsoidal ht. are equivalent.
DJ8953
DJ8953.The ellipsoidal height was determined by GPS observations
DJ8953.and is referenced to NAD 83.
