 DL6474.The coordinates were established by GPS observations
 DL6474.and adjusted by the National Geodetic Survey in June 2021.
 DL6474
 DL6474.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DL6474.been affixed to the stable North American Tectonic Plate. 
 DL6474
 DL6474.The coordinates are valid at the epoch date displayed above
 DL6474.which is a decimal equivalence of Year/Month/Day.
 DL6474
 DL6474.Due to the release of the International GNSS Service (IGS) 2014
 DL6474.realization of the International Terrestrial Reference Frame of 2014
 DL6474.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
 DL6474.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
 DL6474.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
 DL6474.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
 DL6474.currently published epoch of 2010.00.
 DL6474
 DL6474.Additional information on MYCS2 is available at
 DL6474.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

 DL6474.The XYZ, and position/ellipsoidal ht. are equivalent.
 DL6474
 DL6474.The ellipsoidal height was determined by GPS observations
 DL6474.and is referenced to NAD 83.
