DL7653.The coordinates were established by GPS observations
DL7653.and adjusted by the National Geodetic Survey in March 2024.
DL7653
DL7653.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7653.been affixed to the stable North American Tectonic Plate.
DL7653
DL7653.The coordinates are valid at the epoch date displayed above
DL7653.which is a decimal equivalence of Year/Month/Day.
DL7653
DL7653.Due to the release of the International GNSS Service (IGS) 2014
DL7653.realization of the International Terrestrial Reference Frame of 2014
DL7653.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7653.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7653.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7653.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7653.currently published epoch of 2010.00.
DL7653
DL7653.Additional information on MYCS2 is available at
