DP1310.The coordinates were established by GPS observations
DP1310.and adjusted by the National Geodetic Survey in July 2020.
DP1310
DP1310.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP1310.been affixed to the stable North American Tectonic Plate.
DP1310
DP1310.The coordinates are valid at the epoch date displayed above
DP1310.which is a decimal equivalence of Year/Month/Day.
DP1310
DP1310.Due to the release of the International GNSS Service (IGS) 2014
DP1310.realization of the International Terrestrial Reference Frame of 2014
DP1310.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP1310.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP1310.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP1310.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP1310.currently published epoch of 2010.00.
DP1310
DP1310.Additional information on MYCS2 is available at
DP1310.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DP1310
DP1310.The orthometric height was determined by GPS observations and a
DP1310.high-resolution geoid model using precise GPS observation and
DP1310.processing techniques.
DP1310
DP1310.Significant digits in the geoid height do not necessarily reflect accuracy.
DP1310.GEOID18 height accuracy estimate available here.
DP1310
DP1310.The PID for the CORS L1 Phase Center is DR1547.

DP1310.Click photographs - Photos may exist for this station.
DP1310
DP1310.The XYZ, and position/ellipsoidal ht. are equivalent.
DP1310
DP1310.The ellipsoidal height was determined by GPS observations
DP1310.and is referenced to NAD 83.
