DM5960.The coordinates were established by GPS observations
DM5960.and adjusted by the National Geodetic Survey in June 2019.
DM5960
DM5960.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM5960.been affixed to the stable North American Tectonic Plate.
DM5960
DM5960.The coordinates are valid at the epoch date displayed above
DM5960.which is a decimal equivalence of Year/Month/Day.
DM5960
DM5960.Due to the release of the International GNSS Service (IGS) 2014
DM5960.realization of the International Terrestrial Reference Frame of 2014
DM5960.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM5960.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM5960.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM5960.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM5960.currently published epoch of 2010.00.
DM5960
DM5960.Additional information on MYCS2 is available at
DM5960.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM5960
DM5960.The orthometric height was determined by GPS observations and a
DM5960.high-resolution geoid model using precise GPS observation and
DM5960.processing techniques.
DM5960
DM5960.Significant digits in the geoid height do not necessarily reflect accuracy.
DM5960.GEOID18 height accuracy estimate available here.
DM5960
DM5960.The PID for the CORS L1 Phase Center is DM5961.

DM5960
DM5960.The XYZ, and position/ellipsoidal ht. are equivalent.
DM5960
DM5960.The ellipsoidal height was determined by GPS observations
DM5960.and is referenced to NAD 83.
