DL2031.The coordinates were established by GPS observations
DL2031.and adjusted by the National Geodetic Survey in June 2019.
DL2031
DL2031.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL2031.been affixed to the stable North American Tectonic Plate.
DL2031
DL2031.The coordinates are valid at the epoch date displayed above
DL2031.which is a decimal equivalence of Year/Month/Day.
DL2031
DL2031.Due to the release of the International GNSS Service (IGS) 2014
DL2031.realization of the International Terrestrial Reference Frame of 2014
DL2031.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL2031.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL2031.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL2031.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL2031.currently published epoch of 2010.00.
DL2031
DL2031.Additional information on MYCS2 is available at
DL2031.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL2031.Significant digits in the geoid height do not necessarily reflect accuracy.
DL2031.GEOID18 height accuracy estimate available here.

DL2031.The XYZ, and position/ellipsoidal ht. are equivalent.
DL2031
DL2031.The ellipsoidal height was determined by GPS observations
DL2031.and is referenced to NAD 83.
