DL4001.The coordinates were established by GPS observations
DL4001.and adjusted by the National Geodetic Survey in June 2020.
DL4001
DL4001.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL4001.been affixed to the stable North American Tectonic Plate.
DL4001
DL4001.The coordinates are valid at the epoch date displayed above
DL4001.which is a decimal equivalence of Year/Month/Day.
DL4001
DL4001.Due to the release of the International GNSS Service (IGS) 2014
DL4001.realization of the International Terrestrial Reference Frame of 2014
DL4001.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL4001.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL4001.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL4001.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL4001.currently published epoch of 2010.00.
DL4001
DL4001.Additional information on MYCS2 is available at
DL4001.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL4001.Significant digits in the geoid height do not necessarily reflect accuracy.
DL4001.GEOID18 height accuracy estimate available here.

DL4001.The XYZ, and position/ellipsoidal ht. are equivalent.
DL4001
DL4001.The ellipsoidal height was determined by GPS observations
DL4001.and is referenced to NAD 83.
