DM4120.The coordinates were established by GPS observations
DM4120.and adjusted by the National Geodetic Survey in June 2019.
DM4120
DM4120.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM4120.been affixed to the stable North American Tectonic Plate.
DM4120
DM4120.The coordinates are valid at the epoch date displayed above
DM4120.which is a decimal equivalence of Year/Month/Day.
DM4120
DM4120.Due to the release of the International GNSS Service (IGS) 2014
DM4120.realization of the International Terrestrial Reference Frame of 2014
DM4120.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM4120.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM4120.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM4120.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM4120.currently published epoch of 2010.00.
DM4120
DM4120.Additional information on MYCS2 is available at
DM4120.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM4120
DM4120.The orthometric height was determined by GPS observations and a
DM4120.high-resolution geoid model using precise GPS observation and
DM4120.processing techniques.
DM4120
DM4120.Significant digits in the geoid height do not necessarily reflect accuracy.
DM4120.GEOID18 height accuracy estimate available here.
DM4120
DM4120.The PID for the CORS L1 Phase Center is DR7776.

DM4120
DM4120.The XYZ, and position/ellipsoidal ht. are equivalent.
DM4120
DM4120.The ellipsoidal height was determined by GPS observations
DM4120.and is referenced to NAD 83.
