DI2149.The coordinates were established by GPS observations
DI2149.and adjusted by the National Geodetic Survey in June 2019.
DI2149
DI2149.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI2149.been affixed to the stable North American Tectonic Plate.
DI2149
DI2149.The coordinates are valid at the epoch date displayed above
DI2149.which is a decimal equivalence of Year/Month/Day.
DI2149
DI2149.Due to the release of the International GNSS Service (IGS) 2014
DI2149.realization of the International Terrestrial Reference Frame of 2014
DI2149.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI2149.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI2149.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI2149.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI2149.currently published epoch of 2010.00.

DI2149.The XYZ, and position/ellipsoidal ht. are equivalent.
DI2149
DI2149.The ellipsoidal height was determined by GPS observations
DI2149.and is referenced to NAD 83.
