DL8637.The coordinates were established by GPS observations
DL8637.and adjusted by the National Geodetic Survey in June 2019.
DL8637
DL8637.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL8637.been affixed to the stable North American Tectonic Plate.
DL8637
DL8637.The coordinates are valid at the epoch date displayed above
DL8637.which is a decimal equivalence of Year/Month/Day.
DL8637
DL8637.Due to the release of the International GNSS Service (IGS) 2014
DL8637.realization of the International Terrestrial Reference Frame of 2014
DL8637.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL8637.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL8637.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL8637.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL8637.currently published epoch of 2010.00.
DL8637
DL8637.Additional information on MYCS2 is available at
DL8637.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DL8637.Significant digits in the geoid height do not necessarily reflect accuracy.
DL8637.GEOID18 height accuracy estimate available here.

DL8637.Click photographs - Photos may exist for this station.
DL8637
DL8637.The XYZ, and position/ellipsoidal ht. are equivalent.
DL8637
DL8637.The ellipsoidal height was determined by GPS observations
DL8637.and is referenced to NAD 83.
DL8637
DL8637. The following values were computed from the NAD 83(2011) position.
