DF6677.The coordinates were established by GPS observations
DF6677.and adjusted by the National Geodetic Survey in June 2019.
DF6677
DF6677.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF6677.been affixed to the stable North American Tectonic Plate.
DF6677
DF6677.The coordinates are valid at the epoch date displayed above
DF6677.which is a decimal equivalence of Year/Month/Day.
DF6677
DF6677.Due to the release of the International GNSS Service (IGS) 2014
DF6677.realization of the International Terrestrial Reference Frame of 2014
DF6677.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF6677.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF6677.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF6677.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF6677.currently published epoch of 2010.00.
DF6677
DF6677.Additional information on MYCS2 is available at
DF6677.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF6677
DF6677.The orthometric height was determined by differential leveling and
DF6677.adjusted by the NATIONAL GEODETIC SURVEY
DF6677.in May 2008.
DF6677
DF6677.No vertical observational check was made to the station.
DF6677
DF6677.Significant digits in the geoid height do not necessarily reflect accuracy.
DF6677.GEOID18 height accuracy estimate available here.
DF6677
DF6677.The PID for the CORS L1 Phase Center is DG6902.

DF6677.Click photographs - Photos may exist for this station.
DF6677
DF6677.The XYZ, and position/ellipsoidal ht. are equivalent.
DF6677
DF6677.The ellipsoidal height was determined by GPS observations
DF6677.and is referenced to NAD 83.
