DM3501.The coordinates were established by GPS observations
DM3501.and adjusted by the National Geodetic Survey in June 2019.
DM3501
DM3501.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM3501.been affixed to the stable North American Tectonic Plate.
DM3501
DM3501.The coordinates are valid at the epoch date displayed above
DM3501.which is a decimal equivalence of Year/Month/Day.
DM3501
DM3501.Due to the release of the International GNSS Service (IGS) 2014
DM3501.realization of the International Terrestrial Reference Frame of 2014
DM3501.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM3501.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM3501.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM3501.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM3501.currently published epoch of 2010.00.
DM3501
DM3501.Additional information on MYCS2 is available at
DM3501.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM3501.Significant digits in the geoid height do not necessarily reflect accuracy.
DM3501.GEOID18 height accuracy estimate available here.

DM3501.The XYZ, and position/ellipsoidal ht. are equivalent.
DM3501
DM3501.The ellipsoidal height was determined by GPS observations
DM3501.and is referenced to NAD 83.
