DL7635.The coordinates were established by GPS observations
DL7635.and adjusted by the National Geodetic Survey in July 2023.
DL7635
DL7635.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7635.been affixed to the stable North American Tectonic Plate.
DL7635
DL7635.The coordinates are valid at the epoch date displayed above
DL7635.which is a decimal equivalence of Year/Month/Day.
DL7635
DL7635.Due to the release of the International GNSS Service (IGS) 2014
DL7635.realization of the International Terrestrial Reference Frame of 2014
DL7635.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7635.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7635.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7635.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7635.currently published epoch of 2010.00.
DL7635
DL7635.Additional information on MYCS2 is available at
DL7635.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL7635.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7635
DL7635.The ellipsoidal height was determined by GPS observations
DL7635.and is referenced to NAD 83.
