DP1235.The coordinates were established by GPS observations
DP1235.and adjusted by the National Geodetic Survey in July 2020.
DP1235
DP1235.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP1235.been affixed to the stable North American Tectonic Plate.
DP1235
DP1235.The coordinates are valid at the epoch date displayed above
DP1235.which is a decimal equivalence of Year/Month/Day.
DP1235
DP1235.Due to the release of the International GNSS Service (IGS) 2014
DP1235.realization of the International Terrestrial Reference Frame of 2014
DP1235.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP1235.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP1235.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP1235.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP1235.currently published epoch of 2010.00.
DP1235
DP1235.Additional information on MYCS2 is available at
DP1235.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP1235.Significant digits in the geoid height do not necessarily reflect accuracy.
DP1235.GEOID18 height accuracy estimate available here.

DP1235.Click photographs - Photos may exist for this station.
DP1235
DP1235.The XYZ, and position/ellipsoidal ht. are equivalent.
DP1235
DP1235.The ellipsoidal height was determined by GPS observations
DP1235.and is referenced to NAD 83.
