DM7878.The coordinates were established by GPS observations
DM7878.and adjusted by the National Geodetic Survey in June 2019.
DM7878
DM7878.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7878.been affixed to the stable North American Tectonic Plate.
DM7878
DM7878.The coordinates are valid at the epoch date displayed above
DM7878.which is a decimal equivalence of Year/Month/Day.
DM7878
DM7878.Due to the release of the International GNSS Service (IGS) 2014
DM7878.realization of the International Terrestrial Reference Frame of 2014
DM7878.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7878.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7878.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7878.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7878.currently published epoch of 2010.00.
DM7878
DM7878.Additional information on MYCS2 is available at
DM7878.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM7878
DM7878.The orthometric height was determined by GPS observations and a
DM7878.high-resolution geoid model using precise GPS observation and
DM7878.processing techniques.
DM7878
DM7878.Significant digits in the geoid height do not necessarily reflect accuracy.
DM7878.GEOID18 height accuracy estimate available here.
DM7878
DM7878.The PID for the CORS L1 Phase Center is DM7879.

DM7878
DM7878.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7878
DM7878.The ellipsoidal height was determined by GPS observations
DM7878.and is referenced to NAD 83.
