DL3891.The coordinates were established by GPS observations
DL3891.and adjusted by the National Geodetic Survey in June 2019.
DL3891
DL3891.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3891.been affixed to the stable North American Tectonic Plate.
DL3891
DL3891.The coordinates are valid at the epoch date displayed above
DL3891.which is a decimal equivalence of Year/Month/Day.
DL3891
DL3891.Due to the release of the International GNSS Service (IGS) 2014
DL3891.realization of the International Terrestrial Reference Frame of 2014
DL3891.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3891.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3891.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3891.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3891.currently published epoch of 2010.00.
DL3891
DL3891.Additional information on MYCS2 is available at
DL3891.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL3891
DL3891.The orthometric height was determined by GPS observations and a
DL3891.high-resolution geoid model using precise GPS observation and
DL3891.processing techniques.
DL3891
DL3891.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3891.GEOID18 height accuracy estimate available here.
DL3891
DL3891.The PID for the CORS L1 Phase Center is DR1515.

DL3891
DL3891.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3891
DL3891.The ellipsoidal height was determined by GPS observations
DL3891.and is referenced to NAD 83.
