DL7650.The coordinates were established by GPS observations
DL7650.and adjusted by the National Geodetic Survey in June 2019.
DL7650
DL7650.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7650.been affixed to the stable North American Tectonic Plate.
DL7650
DL7650.The coordinates are valid at the epoch date displayed above
DL7650.which is a decimal equivalence of Year/Month/Day.
DL7650
DL7650.Due to the release of the International GNSS Service (IGS) 2014
DL7650.realization of the International Terrestrial Reference Frame of 2014
DL7650.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7650.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7650.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7650.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7650.currently published epoch of 2010.00.
DL7650
DL7650.Additional information on MYCS2 is available at
DL7650.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL7650.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7650
DL7650.The ellipsoidal height was determined by GPS observations
DL7650.and is referenced to NAD 83.
