DI2245.The coordinates were established by GPS observations
DI2245.and adjusted by the National Geodetic Survey in May 2021.
DI2245
DI2245.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI2245.been affixed to the stable North American Tectonic Plate.
DI2245
DI2245.The coordinates are valid at the epoch date displayed above
DI2245.which is a decimal equivalence of Year/Month/Day.
DI2245
DI2245.Due to the release of the International GNSS Service (IGS) 2014
DI2245.realization of the International Terrestrial Reference Frame of 2014
DI2245.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI2245.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI2245.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI2245.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI2245.currently published epoch of 2010.00.
DI2245
DI2245.Additional information on MYCS2 is available at
DI2245.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DI2245
DI2245.The orthometric height was determined by GPS observations and a
DI2245.high-resolution geoid model using precise GPS observation and
DI2245.processing techniques.
DI2245
DI2245.Significant digits in the geoid height do not necessarily reflect accuracy.
DI2245.GEOID18 height accuracy estimate available here.
DI2245
DI2245.The PID for the CORS L1 Phase Center is DQ7757.

DI2245.Click photographs - Photos may exist for this station.
DI2245
DI2245.The XYZ, and position/ellipsoidal ht. are equivalent.
DI2245
DI2245.The ellipsoidal height was determined by GPS observations
DI2245.and is referenced to NAD 83.
