DM4638.The coordinates were established by GPS observations
DM4638.and adjusted by the National Geodetic Survey in June 2019.
DM4638
DM4638.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM4638.been affixed to the stable North American Tectonic Plate.
DM4638
DM4638.The coordinates are valid at the epoch date displayed above
DM4638.which is a decimal equivalence of Year/Month/Day.
DM4638
DM4638.Due to the release of the International GNSS Service (IGS) 2014
DM4638.realization of the International Terrestrial Reference Frame of 2014
DM4638.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM4638.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM4638.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM4638.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM4638.currently published epoch of 2010.00.
DM4638
DM4638.Additional information on MYCS2 is available at
DM4638.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM4638
DM4638.The orthometric height was determined by GPS observations and a
DM4638.high-resolution geoid model using precise GPS observation and
DM4638.processing techniques.
DM4638
DM4638.Significant digits in the geoid height do not necessarily reflect accuracy.
DM4638.GEOID18 height accuracy estimate available here.
DM4638
DM4638.The PID for the CORS L1 Phase Center is DS2873.

DM4638
DM4638.The XYZ, and position/ellipsoidal ht. are equivalent.
DM4638
DM4638.The ellipsoidal height was determined by GPS observations
DM4638.and is referenced to NAD 83.
