DL6678.The coordinates were established by GPS observations
DL6678.and adjusted by the National Geodetic Survey in October 2020.
DL6678
DL6678.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6678.been affixed to the stable North American Tectonic Plate.
DL6678
DL6678.The coordinates are valid at the epoch date displayed above
DL6678.which is a decimal equivalence of Year/Month/Day.
DL6678
DL6678.Due to the release of the International GNSS Service (IGS) 2014
DL6678.realization of the International Terrestrial Reference Frame of 2014
DL6678.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6678.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6678.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6678.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6678.currently published epoch of 2010.00.
DL6678
DL6678.Additional information on MYCS2 is available at
DL6678.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL6678
DL6678.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6678
DL6678.The ellipsoidal height was determined by GPS observations
DL6678.and is referenced to NAD 83.
