DL3498.The coordinates were established by GPS observations
DL3498.and adjusted by the National Geodetic Survey in June 2019.
DL3498
DL3498.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL3498.been affixed to the stable North American Tectonic Plate.
DL3498
DL3498.The coordinates are valid at the epoch date displayed above
DL3498.which is a decimal equivalence of Year/Month/Day.
DL3498
DL3498.Due to the release of the International GNSS Service (IGS) 2014
DL3498.realization of the International Terrestrial Reference Frame of 2014
DL3498.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL3498.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL3498.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL3498.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL3498.currently published epoch of 2010.00.
DL3498
DL3498.Additional information on MYCS2 is available at
DL3498.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL3498.Significant digits in the geoid height do not necessarily reflect accuracy.
DL3498.GEOID18 height accuracy estimate available here.

DL3498.Click photographs - Photos may exist for this station.
DL3498
DL3498.The XYZ, and position/ellipsoidal ht. are equivalent.
DL3498
DL3498.The ellipsoidal height was determined by GPS observations
DL3498.and is referenced to NAD 83.
