DM7125.The coordinates were established by GPS observations
DM7125.and adjusted by the National Geodetic Survey in June 2019.
DM7125
DM7125.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM7125.been affixed to the stable North American Tectonic Plate.
DM7125
DM7125.The coordinates are valid at the epoch date displayed above
DM7125.which is a decimal equivalence of Year/Month/Day.
DM7125
DM7125.Due to the release of the International GNSS Service (IGS) 2014
DM7125.realization of the International Terrestrial Reference Frame of 2014
DM7125.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM7125.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM7125.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM7125.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM7125.currently published epoch of 2010.00.
DM7125
DM7125.Additional information on MYCS2 is available at
DM7125.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM7125
DM7125.The orthometric height was determined by differential leveling and
DM7125.adjusted by the NATIONAL GEODETIC SURVEY
DM7125.in December 2011.
DM7125
DM7125.No vertical observational check was made to the station.
DM7125
DM7125.Significant digits in the geoid height do not necessarily reflect accuracy.
DM7125.GEOID18 height accuracy estimate available here.
DM7125
DM7125.The PID for the CORS L1 Phase Center is DM7126.

DM7125.Click photographs - Photos may exist for this station.
DM7125
DM7125.The XYZ, and position/ellipsoidal ht. are equivalent.
DM7125
DM7125.The ellipsoidal height was determined by GPS observations
DM7125.and is referenced to NAD 83.
