DL3929.The coordinates were established by GPS observations
DL3929.and adjusted by the National Geodetic Survey in May 2021.
DL3929
DL3929.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3929.been affixed to the stable North American Tectonic Plate.
DL3929
DL3929.The coordinates are valid at the epoch date displayed above
DL3929.which is a decimal equivalence of Year/Month/Day.
DL3929
DL3929.Due to the release of the International GNSS Service (IGS) 2014
DL3929.realization of the International Terrestrial Reference Frame of 2014
DL3929.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3929.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3929.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3929.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3929.currently published epoch of 2010.00.
DL3929
DL3929.Additional information on MYCS2 is available at
DL3929.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL3929
DL3929.The orthometric height was determined by GPS observations and a
DL3929.high-resolution geoid model using precise GPS observation and
DL3929.processing techniques.
DL3929
DL3929.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3929.GEOID18 height accuracy estimate available here.
DL3929
DL3929.The PID for the CORS L1 Phase Center is DQ6490.

DL3929.Click photographs - Photos may exist for this station.
DL3929
DL3929.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3929
DL3929.The ellipsoidal height was determined by GPS observations
DL3929.and is referenced to NAD 83.
