DH3874.The coordinates were established by GPS observations
DH3874.and adjusted by the National Geodetic Survey in March 2023.
DH3874
DH3874.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3874.been affixed to the stable North American Tectonic Plate.
DH3874
DH3874.The coordinates are valid at the epoch date displayed above
DH3874.which is a decimal equivalence of Year/Month/Day.
DH3874
DH3874.Due to the release of the International GNSS Service (IGS) 2014
DH3874.realization of the International Terrestrial Reference Frame of 2014
DH3874.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3874.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3874.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3874.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3874.currently published epoch of 2010.00.
DH3874
DH3874.Additional information on MYCS2 is available at
DH3874.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DH3874
DH3874.The orthometric height was determined by GPS observations and a
DH3874.high-resolution geoid model using precise GPS observation and
DH3874.processing techniques.
DH3874
DH3874.Significant digits in the geoid height do not necessarily reflect accuracy.
DH3874.GEOID18 height accuracy estimate available here.
DH3874
DH3874.The PID for the CORS L1 Phase Center is DL7128.

DH3874.Click photographs - Photos may exist for this station.
DH3874
DH3874.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3874
DH3874.The ellipsoidal height was determined by GPS observations
DH3874.and is referenced to NAD 83.
