DL3071.The coordinates were established by GPS observations
DL3071.and adjusted by the National Geodetic Survey in June 2019.
DL3071
DL3071.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3071.been affixed to the stable North American Tectonic Plate.
DL3071
DL3071.The coordinates are valid at the epoch date displayed above
DL3071.which is a decimal equivalence of Year/Month/Day.
DL3071
DL3071.Due to the release of the International GNSS Service (IGS) 2014
DL3071.realization of the International Terrestrial Reference Frame of 2014
DL3071.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3071.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3071.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3071.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3071.currently published epoch of 2010.00.
DL3071
DL3071.Additional information on MYCS2 is available at
DL3071.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL3071
DL3071.The orthometric height was determined by GPS observations and a
DL3071.high-resolution geoid model using precise GPS observation and
DL3071.processing techniques.
DL3071
DL3071.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3071.GEOID18 height accuracy estimate available here.
DL3071
DL3071.The PID for the CORS L1 Phase Center is DR6181.

DL3071
DL3071.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3071
DL3071.The ellipsoidal height was determined by GPS observations
DL3071.and is referenced to NAD 83.
