DL7662.The coordinates were established by GPS observations
DL7662.and adjusted by the National Geodetic Survey in October 2020.
DL7662
DL7662.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7662.been affixed to the stable North American Tectonic Plate.
DL7662
DL7662.The coordinates are valid at the epoch date displayed above
DL7662.which is a decimal equivalence of Year/Month/Day.
DL7662
DL7662.Due to the release of the International GNSS Service (IGS) 2014
DL7662.realization of the International Terrestrial Reference Frame of 2014
DL7662.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7662.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7662.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7662.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7662.currently published epoch of 2010.00.
DL7662
DL7662.Additional information on MYCS2 is available at
DL7662.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL7662.Significant digits in the geoid height do not necessarily reflect accuracy.

DL7662.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7662
DL7662.The ellipsoidal height was determined by GPS observations
DL7662.and is referenced to NAD 83.
