DL6155.The coordinates were established by GPS observations
DL6155.and adjusted by the National Geodetic Survey in June 2019.
DL6155
DL6155.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6155.been affixed to the stable North American Tectonic Plate.
DL6155
DL6155.The coordinates are valid at the epoch date displayed above
DL6155.which is a decimal equivalence of Year/Month/Day.
DL6155
DL6155.Due to the release of the International GNSS Service (IGS) 2014
DL6155.realization of the International Terrestrial Reference Frame of 2014
DL6155.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6155.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6155.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6155.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6155.currently published epoch of 2010.00.
DL6155
DL6155.Additional information on MYCS2 is available at
DL6155.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL6155.Significant digits in the geoid height do not necessarily reflect accuracy.
DL6155.GEOID18 height accuracy estimate available here.

DL6155.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6155
DL6155.The ellipsoidal height was determined by GPS observations
DL6155.and is referenced to NAD 83.
