DI1878.The coordinates were established by GPS observations
DI1878.and adjusted by the National Geodetic Survey in May 2021.
DI1878
DI1878.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI1878.been affixed to the stable North American Tectonic Plate.
DI1878
DI1878.The coordinates are valid at the epoch date displayed above
DI1878.which is a decimal equivalence of Year/Month/Day.
DI1878
DI1878.Due to the release of the International GNSS Service (IGS) 2014
DI1878.realization of the International Terrestrial Reference Frame of 2014
DI1878.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI1878.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI1878.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI1878.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI1878.currently published epoch of 2010.00.
DI1878
DI1878.Additional information on MYCS2 is available at
DI1878.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI1878.Significant digits in the geoid height do not necessarily reflect accuracy.
DI1878.GEOID18 height accuracy estimate available here.

DI1878.Click photographs - Photos may exist for this station.
DI1878
DI1878.The XYZ, and position/ellipsoidal ht. are equivalent.
DI1878
DI1878.The ellipsoidal height was determined by GPS observations
DI1878.and is referenced to NAD 83.
