DI3824.The coordinates were established by GPS observations
DI3824.and adjusted by the National Geodetic Survey in December 2022.
DI3824
DI3824.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI3824.been affixed to the stable North American Tectonic Plate.
DI3824
DI3824.The coordinates are valid at the epoch date displayed above
DI3824.which is a decimal equivalence of Year/Month/Day.
DI3824
DI3824.Due to the release of the International GNSS Service (IGS) 2014
DI3824.realization of the International Terrestrial Reference Frame of 2014
DI3824.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI3824.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI3824.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI3824.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI3824.currently published epoch of 2010.00.
DI3824
DI3824.Additional information on MYCS2 is available at
DI3824.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DI3824
DI3824.The orthometric height was determined by differential leveling and
DI3824.adjusted by the NATIONAL GEODETIC SURVEY
DI3824.in August 2012.
DI3824
DI3824.No vertical observational check was made to the station.
DI3824
DI3824.Significant digits in the geoid height do not necessarily reflect accuracy.
DI3824.GEOID18 height accuracy estimate available here.
DI3824
DI3824.The PID for the CORS L1 Phase Center is DR8310.

DI3824.Click photographs - Photos may exist for this station.
DI3824
DI3824.The XYZ, and position/ellipsoidal ht. are equivalent.
DI3824
DI3824.The ellipsoidal height was determined by GPS observations
DI3824.and is referenced to NAD 83.
