DM2694.The coordinates were established by GPS observations
DM2694.and adjusted by the National Geodetic Survey in June 2019.
DM2694
DM2694.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM2694.been affixed to the stable North American Tectonic Plate.
DM2694
DM2694.The coordinates are valid at the epoch date displayed above
DM2694.which is a decimal equivalence of Year/Month/Day.
DM2694
DM2694.Due to the release of the International GNSS Service (IGS) 2014
DM2694.realization of the International Terrestrial Reference Frame of 2014
DM2694.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM2694.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM2694.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM2694.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM2694.currently published epoch of 2010.00.
DM2694
DM2694.Additional information on MYCS2 is available at
DM2694.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM2694
DM2694.The orthometric height was determined by GPS observations and a
DM2694.high-resolution geoid model using precise GPS observation and
DM2694.processing techniques.
DM2694
DM2694.Significant digits in the geoid height do not necessarily reflect accuracy.
DM2694.GEOID18 height accuracy estimate available here.
DM2694
DM2694.The PID for the CORS L1 Phase Center is DM2695.

DM2694
DM2694.The XYZ, and position/ellipsoidal ht. are equivalent.
DM2694
DM2694.The ellipsoidal height was determined by GPS observations
DM2694.and is referenced to NAD 83.
