DI0624.The coordinates were established by GPS observations
DI0624.and adjusted by the National Geodetic Survey in June 2019.
DI0624
DI0624.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI0624.been affixed to the stable North American Tectonic Plate.
DI0624
DI0624.The coordinates are valid at the epoch date displayed above
DI0624.which is a decimal equivalence of Year/Month/Day.
DI0624
DI0624.Due to the release of the International GNSS Service (IGS) 2014
DI0624.realization of the International Terrestrial Reference Frame of 2014
DI0624.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI0624.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI0624.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI0624.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI0624.currently published epoch of 2010.00.
DI0624
DI0624.Additional information on MYCS2 is available at
DI0624.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DI0624
DI0624.The orthometric height was determined by differential leveling and
DI0624.adjusted by the NATIONAL GEODETIC SURVEY
DI0624.in April 2010.
DI0624
DI0624.No vertical observational check was made to the station.
DI0624
DI0624.Significant digits in the geoid height do not necessarily reflect accuracy.
DI0624.GEOID18 height accuracy estimate available here.
DI0624
DI0624.The PID for the CORS L1 Phase Center is DO9492.

DI0624.Click photographs - Photos may exist for this station.
DI0624
DI0624.The XYZ, and position/ellipsoidal ht. are equivalent.
DI0624
DI0624.The ellipsoidal height was determined by GPS observations
DI0624.and is referenced to NAD 83.
