DL6165.The coordinates were established by GPS observations
DL6165.and adjusted by the National Geodetic Survey in June 2019.
DL6165
DL6165.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6165.been affixed to the stable North American Tectonic Plate.
DL6165
DL6165.The coordinates are valid at the epoch date displayed above
DL6165.which is a decimal equivalence of Year/Month/Day.
DL6165
DL6165.Due to the release of the International GNSS Service (IGS) 2014
DL6165.realization of the International Terrestrial Reference Frame of 2014
DL6165.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6165.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6165.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6165.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6165.currently published epoch of 2010.00.
DL6165
DL6165.Additional information on MYCS2 is available at
DL6165.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL6165.Significant digits in the geoid height do not necessarily reflect accuracy.
DL6165.GEOID18 height accuracy estimate available here.

DL6165.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6165
DL6165.The ellipsoidal height was determined by GPS observations
DL6165.and is referenced to NAD 83.
