DH3610.The coordinates were established by GPS observations
DH3610.and adjusted by the National Geodetic Survey in April 2022.
DH3610
DH3610.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3610.been affixed to the stable North American Tectonic Plate.
DH3610
DH3610.The coordinates are valid at the epoch date displayed above
DH3610.which is a decimal equivalence of Year/Month/Day.
DH3610
DH3610.Due to the release of the International GNSS Service (IGS) 2014
DH3610.realization of the International Terrestrial Reference Frame of 2014
DH3610.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3610.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3610.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3610.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3610.currently published epoch of 2010.00.
DH3610
DH3610.Additional information on MYCS2 is available at
DH3610.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH3610
DH3610.The orthometric height was determined by GPS observations and a
DH3610.high-resolution geoid model using precise GPS observation and
DH3610.processing techniques.
DH3610
DH3610.Significant digits in the geoid height do not necessarily reflect accuracy.
DH3610.GEOID18 height accuracy estimate available here.
DH3610
DH3610.The PID for the CORS L1 Phase Center is DR7676.

DH3610.Click photographs - Photos may exist for this station.
DH3610
DH3610.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3610
DH3610.The ellipsoidal height was determined by GPS observations
DH3610.and is referenced to NAD 83.
