DM7499.The coordinates were established by GPS observations
DM7499.and adjusted by the National Geodetic Survey in February 2020.
DM7499
DM7499.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7499.been affixed to the stable North American Tectonic Plate.
DM7499
DM7499.The coordinates are valid at the epoch date displayed above
DM7499.which is a decimal equivalence of Year/Month/Day.
DM7499
DM7499.Due to the release of the International GNSS Service (IGS) 2014
DM7499.realization of the International Terrestrial Reference Frame of 2014
DM7499.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7499.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7499.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7499.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7499.currently published epoch of 2010.00.
