DH3580.The coordinates were established by GPS observations
DH3580.and adjusted by the National Geodetic Survey in June 2019.
DH3580
DH3580.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3580.been affixed to the stable North American Tectonic Plate.
DH3580
DH3580.The coordinates are valid at the epoch date displayed above
DH3580.which is a decimal equivalence of Year/Month/Day.
DH3580
DH3580.Due to the release of the International GNSS Service (IGS) 2014
DH3580.realization of the International Terrestrial Reference Frame of 2014
DH3580.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3580.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3580.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3580.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3580.currently published epoch of 2010.00.
DH3580
DH3580.Additional information on MYCS2 is available at
DH3580.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH3580
DH3580.The orthometric height was determined by GPS observations and a
DH3580.high-resolution geoid model using precise GPS observation and
DH3580.processing techniques.
DH3580
DH3580.Significant digits in the geoid height do not necessarily reflect accuracy.
DH3580.GEOID18 height accuracy estimate available here.
DH3580
DH3580.The PID for the CORS L1 Phase Center is DM9834.

DH3580.Click photographs - Photos may exist for this station.
DH3580
DH3580.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3580
DH3580.The ellipsoidal height was determined by GPS observations
DH3580.and is referenced to NAD 83.
