DI2108.The coordinates were established by GPS observations
DI2108.and adjusted by the National Geodetic Survey in June 2019.
DI2108
DI2108.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI2108.been affixed to the stable North American Tectonic Plate.
DI2108
DI2108.The coordinates are valid at the epoch date displayed above
DI2108.which is a decimal equivalence of Year/Month/Day.
DI2108
DI2108.Due to the release of the International GNSS Service (IGS) 2014
DI2108.realization of the International Terrestrial Reference Frame of 2014
DI2108.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI2108.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI2108.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI2108.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI2108.currently published epoch of 2010.00.
DI2108
DI2108.Additional information on MYCS2 is available at
DI2108.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI2108.Significant digits in the geoid height do not necessarily reflect accuracy.
DI2108.GEOID18 height accuracy estimate available here.

DI2108.The PID for the CORS L1 Phase Center is DI2109.

DI2108.Click photographs - Photos may exist for this station.
DI2108
DI2108.The XYZ, and position/ellipsoidal ht. are equivalent.
DI2108
DI2108.The ellipsoidal height was determined by GPS observations
DI2108.and is referenced to NAD 83.
