DM3487.The coordinates were established by GPS observations
DM3487.and adjusted by the National Geodetic Survey in April 2020.
DM3487
DM3487.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM3487.been affixed to the stable North American Tectonic Plate.
DM3487
DM3487.The coordinates are valid at the epoch date displayed above
DM3487.which is a decimal equivalence of Year/Month/Day.
DM3487
DM3487.Due to the release of the International GNSS Service (IGS) 2014
DM3487.realization of the International Terrestrial Reference Frame of 2014
DM3487.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM3487.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM3487.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM3487.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM3487.currently published epoch of 2010.00.
DM3487
DM3487.Additional information on MYCS2 is available at
DM3487.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DM3487.Significant digits in the geoid height do not necessarily reflect accuracy.
DM3487.GEOID18 height accuracy estimate available here.

DM3487.The PID for the CORS L1 Phase Center is DR1524.

DM3487.The XYZ, and position/ellipsoidal ht. are equivalent.
DM3487
DM3487.The ellipsoidal height was determined by GPS observations
DM3487.and is referenced to NAD 83.
