DP1233.The coordinates were established by GPS observations
DP1233.and adjusted by the National Geodetic Survey in May 2020.
DP1233
DP1233.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP1233.been affixed to the stable North American Tectonic Plate.
DP1233
DP1233.The coordinates are valid at the epoch date displayed above
DP1233.which is a decimal equivalence of Year/Month/Day.
DP1233
DP1233.Due to the release of the International GNSS Service (IGS) 2014
DP1233.realization of the International Terrestrial Reference Frame of 2014
DP1233.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP1233.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP1233.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP1233.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP1233.currently published epoch of 2010.00.
DP1233
DP1233.Additional information on MYCS2 is available at
DP1233.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DP1233.Significant digits in the geoid height do not necessarily reflect accuracy.
DP1233.GEOID18 height accuracy estimate available here.

DP1233.Click photographs - Photos may exist for this station.
DP1233
DP1233.The XYZ, and position/ellipsoidal ht. are equivalent.
DP1233
DP1233.The ellipsoidal height was determined by GPS observations
DP1233.and is referenced to NAD 83.
