DL6695.The coordinates were established by GPS observations
DL6695.and adjusted by the National Geodetic Survey in July 2023.
DL6695
DL6695.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6695.been affixed to the stable North American Tectonic Plate.
DL6695
DL6695.The coordinates are valid at the epoch date displayed above
DL6695.which is a decimal equivalence of Year/Month/Day.
DL6695
DL6695.Due to the release of the International GNSS Service (IGS) 2014
DL6695.realization of the International Terrestrial Reference Frame of 2014
DL6695.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6695.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6695.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6695.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6695.currently published epoch of 2010.00.
DL6695
DL6695.Additional information on MYCS2 is available at
DL6695.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL6695.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6695
DL6695.The ellipsoidal height was determined by GPS observations
DL6695.and is referenced to NAD 83.
