DL3188.The coordinates were established by GPS observations
DL3188.and adjusted by the National Geodetic Survey in June 2019.
DL3188
DL3188.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3188.been affixed to the stable North American Tectonic Plate.
DL3188
DL3188.The coordinates are valid at the epoch date displayed above
DL3188.which is a decimal equivalence of Year/Month/Day.
DL3188
DL3188.Due to the release of the International GNSS Service (IGS) 2014
DL3188.realization of the International Terrestrial Reference Frame of 2014
DL3188.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3188.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3188.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3188.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3188.currently published epoch of 2010.00.
DL3188
DL3188.Additional information on MYCS2 is available at
DL3188.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL3188.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3188.GEOID18 height accuracy estimate available here.

DL3188.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3188
DL3188.The ellipsoidal height was determined by GPS observations
DL3188.and is referenced to NAD 83.
