DM3995.The coordinates were established by GPS observations
DM3995.and adjusted by the National Geodetic Survey in June 2019.
DM3995
DM3995.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM3995.been affixed to the stable North American Tectonic Plate.
DM3995
DM3995.The coordinates are valid at the epoch date displayed above
DM3995.which is a decimal equivalence of Year/Month/Day.
DM3995
DM3995.Due to the release of the International GNSS Service (IGS) 2014
DM3995.realization of the International Terrestrial Reference Frame of 2014
DM3995.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM3995.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM3995.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM3995.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM3995.currently published epoch of 2010.00.
DM3995
DM3995.Additional information on MYCS2 is available at
DM3995.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM3995
DM3995.The orthometric height was determined by GPS observations and a
DM3995.high-resolution geoid model using precise GPS observation and
DM3995.processing techniques.
DM3995
DM3995.Significant digits in the geoid height do not necessarily reflect accuracy.
DM3995.GEOID18 height accuracy estimate available here.
DM3995
DM3995.The PID for the CORS L1 Phase Center is DR9311.

DM3995.Click photographs - Photos may exist for this station.
DM3995
DM3995.The XYZ, and position/ellipsoidal ht. are equivalent.
DM3995
DM3995.The ellipsoidal height was determined by GPS observations
DM3995.and is referenced to NAD 83.
