DL6908.The coordinates were established by GPS observations
DL6908.and adjusted by the National Geodetic Survey in July 2023.
DL6908
DL6908.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6908.been affixed to the stable North American Tectonic Plate.
DL6908
DL6908.The coordinates are valid at the epoch date displayed above
DL6908.which is a decimal equivalence of Year/Month/Day.
DL6908
DL6908.Due to the release of the International GNSS Service (IGS) 2014
DL6908.realization of the International Terrestrial Reference Frame of 2014
DL6908.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6908.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6908.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6908.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6908.currently published epoch of 2010.00.
DL6908
DL6908.Additional information on MYCS2 is available at
DL6908.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL6908.Significant digits in the geoid height do not necessarily reflect accuracy.
DL6908.GEOID18 height accuracy estimate available here.

DL6908.Click photographs - Photos may exist for this station.
DL6908
DL6908.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6908
DL6908.The ellipsoidal height was determined by GPS observations
DL6908.and is referenced to NAD 83.
