DL6900.The coordinates were established by GPS observations
DL6900.and adjusted by the National Geodetic Survey in June 2019.
DL6900
DL6900.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6900.been affixed to the stable North American Tectonic Plate.
DL6900
DL6900.The coordinates are valid at the epoch date displayed above
DL6900.which is a decimal equivalence of Year/Month/Day.
DL6900
DL6900.Due to the release of the International GNSS Service (IGS) 2014
DL6900.realization of the International Terrestrial Reference Frame of 2014
DL6900.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6900.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6900.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6900.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6900.currently published epoch of 2010.00.
DL6900
DL6900.Additional information on MYCS2 is available at
DL6900.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL6900
DL6900.The orthometric height was determined by GPS observations and a
DL6900.high-resolution geoid model using precise GPS observation and
DL6900.processing techniques.
DL6900
DL6900.Significant digits in the geoid height do not necessarily reflect accuracy.
DL6900.GEOID18 height accuracy estimate available here.
DL6900
DL6900.The PID for the CORS L1 Phase Center is DS2835.

DL6900
DL6900.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6900
DL6900.The ellipsoidal height was determined by GPS observations
DL6900.and is referenced to NAD 83.
