DI1840.The coordinates were established by GPS observations
DI1840.and adjusted by the National Geodetic Survey in June 2019.
DI1840
DI1840.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI1840.been affixed to the stable North American Tectonic Plate.
DI1840
DI1840.The coordinates are valid at the epoch date displayed above
DI1840.which is a decimal equivalence of Year/Month/Day.
DI1840
DI1840.Due to the release of the International GNSS Service (IGS) 2014
DI1840.realization of the International Terrestrial Reference Frame of 2014
DI1840.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI1840.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI1840.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI1840.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI1840.currently published epoch of 2010.00.
DI1840
DI1840.Additional information on MYCS2 is available at
DI1840.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI1840.Significant digits in the geoid height do not necessarily reflect accuracy.
DI1840.GEOID18 height accuracy estimate available here.

DI1840.The PID for the CORS L1 Phase Center is DQ6465.

DI1840.Click photographs - Photos may exist for this station.
DI1840
DI1840.The XYZ, and position/ellipsoidal ht. are equivalent.
DI1840
DI1840.The ellipsoidal height was determined by GPS observations
DI1840.and is referenced to NAD 83.
