DP2488.The coordinates were established by GPS observations
DP2488.and adjusted by the National Geodetic Survey in May 2020.
DP2488
DP2488.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP2488.been affixed to the stable North American Tectonic Plate.
DP2488
DP2488.The coordinates are valid at the epoch date displayed above
DP2488.which is a decimal equivalence of Year/Month/Day.
DP2488
DP2488.Due to the release of the International GNSS Service (IGS) 2014
DP2488.realization of the International Terrestrial Reference Frame of 2014
DP2488.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP2488.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP2488.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP2488.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP2488.currently published epoch of 2010.00.
DP2488
DP2488.Additional information on MYCS2 is available at
DP2488.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DP2488
DP2488.The orthometric height was determined by GPS observations and a
DP2488.high-resolution geoid model using precise GPS observation and
DP2488.processing techniques.
DP2488
DP2488.Significant digits in the geoid height do not necessarily reflect accuracy.
DP2488.GEOID18 height accuracy estimate available here.
DP2488
DP2488.The PID for the CORS L1 Phase Center is DR1551.

DP2488.Click photographs - Photos may exist for this station.
DP2488
DP2488.The XYZ, and position/ellipsoidal ht. are equivalent.
DP2488
DP2488.The ellipsoidal height was determined by GPS observations
DP2488.and is referenced to NAD 83.
