DI8408.The coordinates were established by GPS observations
DI8408.and adjusted by the National Geodetic Survey in June 2019.
DI8408
DI8408.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI8408.been affixed to the stable North American Tectonic Plate.
DI8408
DI8408.The coordinates are valid at the epoch date displayed above
DI8408.which is a decimal equivalence of Year/Month/Day.
DI8408
DI8408.Due to the release of the International GNSS Service (IGS) 2014
DI8408.realization of the International Terrestrial Reference Frame of 2014
DI8408.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI8408.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI8408.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI8408.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI8408.currently published epoch of 2010.00.
DI8408
DI8408.Additional information on MYCS2 is available at
DI8408.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DI8408.Significant digits in the geoid height do not necessarily reflect accuracy.
DI8408.GEOID18 height accuracy estimate available here.

DI8408.Click photographs - Photos may exist for this station.
DI8408
DI8408.The XYZ, and position/ellipsoidal ht. are equivalent.
DI8408
DI8408.The ellipsoidal height was determined by GPS observations
DI8408.and is referenced to NAD 83.
