DP3838.The coordinates were established by GPS observations
DP3838.and adjusted by the National Geodetic Survey in June 2019.
DP3838
DP3838.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP3838.been affixed to the stable North American Tectonic Plate.
DP3838
DP3838.The coordinates are valid at the epoch date displayed above
DP3838.which is a decimal equivalence of Year/Month/Day.
DP3838
DP3838.Due to the release of the International GNSS Service (IGS) 2014
DP3838.realization of the International Terrestrial Reference Frame of 2014
DP3838.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP3838.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP3838.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP3838.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP3838.currently published epoch of 2010.00.
DP3838
DP3838.Additional information on MYCS2 is available at
DP3838.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP3838.Significant digits in the geoid height do not necessarily reflect accuracy.
DP3838.GEOID12B height accuracy estimate available here.

DP3838.Click photographs - Photos may exist for this station.
DP3838
DP3838.The XYZ, and position/ellipsoidal ht. are equivalent.
DP3838
DP3838.The ellipsoidal height was determined by GPS observations
DP3838.and is referenced to NAD 83.
