DI1848.The coordinates were established by GPS observations
DI1848.and adjusted by the National Geodetic Survey in June 2019.
DI1848
DI1848.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI1848.been affixed to the stable North American Tectonic Plate.
DI1848
DI1848.The coordinates are valid at the epoch date displayed above
DI1848.which is a decimal equivalence of Year/Month/Day.
DI1848
DI1848.Due to the release of the International GNSS Service (IGS) 2014
DI1848.realization of the International Terrestrial Reference Frame of 2014
DI1848.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI1848.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI1848.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI1848.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI1848.currently published epoch of 2010.00.
DI1848
DI1848.Additional information on MYCS2 is available at
DI1848.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI1848.Significant digits in the geoid height do not necessarily reflect accuracy.
DI1848.GEOID18 height accuracy estimate available here.

DI1848.Click photographs - Photos may exist for this station.
DI1848
DI1848.The XYZ, and position/ellipsoidal ht. are equivalent.
DI1848
DI1848.The ellipsoidal height was determined by GPS observations
DI1848.and is referenced to NAD 83.
