DL7683.The coordinates were established by GPS observations
DL7683.and adjusted by the National Geodetic Survey in May 2021.
DL7683
DL7683.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7683.been affixed to the stable North American Tectonic Plate.
DL7683
DL7683.The coordinates are valid at the epoch date displayed above
DL7683.which is a decimal equivalence of Year/Month/Day.
DL7683
DL7683.Due to the release of the International GNSS Service (IGS) 2014
DL7683.realization of the International Terrestrial Reference Frame of 2014
DL7683.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7683.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7683.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7683.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7683.currently published epoch of 2010.00.
DL7683
DL7683.Additional information on MYCS2 is available at
DL7683.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL7683.Significant digits in the geoid height do not necessarily reflect accuracy.
DL7683.GEOID18 height accuracy estimate available here.

DL7683.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7683
DL7683.The ellipsoidal height was determined by GPS observations
DL7683.and is referenced to NAD 83.
