DH7127.The coordinates were established by GPS observations
DH7127.and adjusted by the National Geodetic Survey in June 2020.
DH7127
DH7127.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH7127.been affixed to the stable North American Tectonic Plate.
DH7127
DH7127.The coordinates are valid at the epoch date displayed above
DH7127.which is a decimal equivalence of Year/Month/Day.
DH7127
DH7127.Due to the release of the International GNSS Service (IGS) 2014
DH7127.realization of the International Terrestrial Reference Frame of 2014
DH7127.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH7127.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH7127.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH7127.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH7127.currently published epoch of 2010.00.
DH7127
DH7127.Additional information on MYCS2 is available at
DH7127.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH7127
DH7127.The orthometric height was determined by GPS observations and a
DH7127.high-resolution geoid model using precise GPS observation and
DH7127.processing techniques.
DH7127
DH7127.Significant digits in the geoid height do not necessarily reflect accuracy.
DH7127.GEOID18 height accuracy estimate available here.
DH7127
DH7127.The PID for the CORS L1 Phase Center is DR5945.

DH7127.Click photographs - Photos may exist for this station.
DH7127
DH7127.The XYZ, and position/ellipsoidal ht. are equivalent.
DH7127
DH7127.The ellipsoidal height was determined by GPS observations
DH7127.and is referenced to NAD 83.
