DI1075.The coordinates were established by GPS observations
DI1075.and adjusted by the National Geodetic Survey in April 2022.
DI1075
DI1075.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI1075.been affixed to the stable North American Tectonic Plate.
DI1075
DI1075.The coordinates are valid at the epoch date displayed above
DI1075.which is a decimal equivalence of Year/Month/Day.
DI1075
DI1075.Due to the release of the International GNSS Service (IGS) 2014
DI1075.realization of the International Terrestrial Reference Frame of 2014
DI1075.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI1075.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI1075.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI1075.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI1075.currently published epoch of 2010.00.
DI1075
DI1075.Additional information on MYCS2 is available at
DI1075.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DI1075
DI1075.The orthometric height was determined by GPS observations and a
DI1075.high-resolution geoid model using precise GPS observation and
DI1075.processing techniques.
DI1075
DI1075.Significant digits in the geoid height do not necessarily reflect accuracy.
DI1075.GEOID18 height accuracy estimate available here.
DI1075
DI1075.The PID for the CORS L1 Phase Center is DR9281.

DI1075.Click photographs - Photos may exist for this station.
DI1075
DI1075.The XYZ, and position/ellipsoidal ht. are equivalent.
DI1075
DI1075.The ellipsoidal height was determined by GPS observations
DI1075.and is referenced to NAD 83.
