DI0446.The coordinates were established by GPS observations
DI0446.and adjusted by the National Geodetic Survey in June 2019.
DI0446
DI0446.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI0446.been affixed to the stable North American Tectonic Plate.
DI0446
DI0446.The coordinates are valid at the epoch date displayed above
DI0446.which is a decimal equivalence of Year/Month/Day.
DI0446
DI0446.Due to the release of the International GNSS Service (IGS) 2014
DI0446.realization of the International Terrestrial Reference Frame of 2014
DI0446.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI0446.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI0446.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI0446.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI0446.currently published epoch of 2010.00.
DI0446
DI0446.Additional information on MYCS2 is available at
DI0446.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DI0446
DI0446.The orthometric height was determined by differential leveling and
DI0446.adjusted by the NATIONAL GEODETIC SURVEY
DI0446.in January 2010.
DI0446
DI0446.No vertical observational check was made to the station.
DI0446
DI0446.Significant digits in the geoid height do not necessarily reflect accuracy.
DI0446.GEOID18 height accuracy estimate available here.
DI0446
DI0446.The PID for the CORS L1 Phase Center is DP2655.
DI0446
DI0446.Click photographs - Photos may exist for this station.
DI0446
DI0446.The XYZ, and position/ellipsoidal ht. are equivalent.
DI0446
DI0446.The ellipsoidal height was determined by GPS observations
DI0446.and is referenced to NAD 83.
