DL7329.The coordinates were established by GPS observations
DL7329.and adjusted by the National Geodetic Survey in June 2019.
DL7329
DL7329.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL7329.been affixed to the stable North American Tectonic Plate.
DL7329
DL7329.The coordinates are valid at the epoch date displayed above
DL7329.which is a decimal equivalence of Year/Month/Day.
DL7329
DL7329.Due to the release of the International GNSS Service (IGS) 2014
DL7329.realization of the International Terrestrial Reference Frame of 2014
DL7329.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL7329.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL7329.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL7329.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL7329.currently published epoch of 2010.00.
DL7329
DL7329.Additional information on MYCS2 is available at
DL7329.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL7329
DL7329.The orthometric height was determined by differential leveling and
DL7329.adjusted by the NATIONAL GEODETIC SURVEY
DL7329.in December 2011.
DL7329
DL7329.No vertical observational check was made to the station.
DL7329
DL7329.Significant digits in the geoid height do not necessarily reflect accuracy.
DL7329.GEOID18 height accuracy estimate available here.
DL7329
DL7329.The PID for the CORS L1 Phase Center is DO1574.

DL7329.Click photographs - Photos may exist for this station.
DL7329
DL7329.The XYZ, and position/ellipsoidal ht. are equivalent.
DL7329
DL7329.The ellipsoidal height was determined by GPS observations
DL7329.and is referenced to NAD 83.
DL7329
DL7329. The following values were computed from the NAD 83(2011) position.
