DM3991.The coordinates were established by GPS observations
DM3991.and adjusted by the National Geodetic Survey in July 2023.
DM3991
DM3991.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM3991.been affixed to the stable North American Tectonic Plate.
DM3991
DM3991.The coordinates are valid at the epoch date displayed above
DM3991.which is a decimal equivalence of Year/Month/Day.
DM3991
DM3991.Due to the release of the International GNSS Service (IGS) 2014
DM3991.realization of the International Terrestrial Reference Frame of 2014
DM3991.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM3991.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM3991.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM3991.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM3991.currently published epoch of 2010.00.
DM3991
DM3991.Additional information on MYCS2 is available at
DM3991.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM3991
DM3991.The orthometric height was determined by GPS observations and a
DM3991.high-resolution geoid model using precise GPS observation and
DM3991.processing techniques.
DM3991
DM3991.Significant digits in the geoid height do not necessarily reflect accuracy.
DM3991.GEOID18 height accuracy estimate available here.
DM3991
DM3991.The PID for the CORS L1 Phase Center is DS2863.

DM3991.The XYZ, and position/ellipsoidal ht. are equivalent.
DM3991
DM3991.The ellipsoidal height was determined by GPS observations
DM3991.and is referenced to NAD 83.
