DI8416.The coordinates were established by GPS observations
DI8416.and adjusted by the National Geodetic Survey in June 2019.
DI8416
DI8416.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI8416.been affixed to the stable North American Tectonic Plate.
DI8416
DI8416.The coordinates are valid at the epoch date displayed above
DI8416.which is a decimal equivalence of Year/Month/Day.
DI8416
DI8416.Due to the release of the International GNSS Service (IGS) 2014
DI8416.realization of the International Terrestrial Reference Frame of 2014
DI8416.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI8416.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI8416.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI8416.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI8416.currently published epoch of 2010.00.
DI8416
DI8416.Additional information on MYCS2 is available at
DI8416.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI8416.Significant digits in the geoid height do not necessarily reflect accuracy.
DI8416.GEOID18 height accuracy estimate available here.

DI8416.Click photographs - Photos may exist for this station.
DI8416
DI8416.The XYZ, and position/ellipsoidal ht. are equivalent.
DI8416
DI8416.The ellipsoidal height was determined by GPS observations
DI8416.and is referenced to NAD 83.
