AJ7208.The coordinates were established by GPS observations
AJ7208.and adjusted by the National Geodetic Survey in June 2019.
AJ7208
AJ7208.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ7208.been affixed to the stable North American Tectonic Plate.
AJ7208
AJ7208.The coordinates are valid at the epoch date displayed above
AJ7208.which is a decimal equivalence of Year/Month/Day.
AJ7208
AJ7208.Due to the release of the International GNSS Service (IGS) 2014
AJ7208.realization of the International Terrestrial Reference Frame of 2014
AJ7208.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ7208.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ7208.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ7208.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ7208.currently published epoch of 2010.00.
AJ7208
AJ7208.Additional information on MYCS2 is available at
AJ7208.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
AJ7208
AJ7208.The orthometric height was determined by differential leveling and
AJ7208.adjusted by the NATIONAL GEODETIC SURVEY
AJ7208.in July 2005.
AJ7208
AJ7208.No vertical observational check was made to the station.
AJ7208
AJ7208.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ7208.GEOID18 height accuracy estimate available here.
AJ7208
AJ7208.The PID for the CORS L1 Phase Center is DN9083.

AJ7208.Click photographs - Photos may exist for this station.
AJ7208
AJ7208.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ7208
AJ7208.The ellipsoidal height was determined by GPS observations
AJ7208.and is referenced to NAD 83.
