DL6651.The coordinates were established by GPS observations
DL6651.and adjusted by the National Geodetic Survey in June 2019.
DL6651
DL6651.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6651.been affixed to the stable North American Tectonic Plate.
DL6651
DL6651.The coordinates are valid at the epoch date displayed above
DL6651.which is a decimal equivalence of Year/Month/Day.
DL6651
DL6651.Due to the release of the International GNSS Service (IGS) 2014
DL6651.realization of the International Terrestrial Reference Frame of 2014
DL6651.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6651.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6651.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6651.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6651.currently published epoch of 2010.00.
DL6651
DL6651.Additional information on MYCS2 is available at
DL6651.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL6651.Significant digits in the geoid height do not necessarily reflect accuracy.

DL6651.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6651
DL6651.The ellipsoidal height was determined by GPS observations
DL6651.and is referenced to NAD 83.
