DL2754.The coordinates were established by GPS observations
DL2754.and adjusted by the National Geodetic Survey in June 2019.
DL2754
DL2754.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL2754.been affixed to the stable North American Tectonic Plate.
DL2754
DL2754.The coordinates are valid at the epoch date displayed above
DL2754.which is a decimal equivalence of Year/Month/Day.
DL2754
DL2754.Due to the release of the International GNSS Service (IGS) 2014
DL2754.realization of the International Terrestrial Reference Frame of 2014
DL2754.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL2754.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL2754.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL2754.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL2754.currently published epoch of 2010.00.
DL2754
DL2754.Additional information on MYCS2 is available at
DL2754.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL2754.Significant digits in the geoid height do not necessarily reflect accuracy.

DL2754.The XYZ, and position/ellipsoidal ht. are equivalent.
DL2754
DL2754.The ellipsoidal height was determined by GPS observations
DL2754.and is referenced to NAD 83.
