DL6649.The coordinates were established by GPS observations
DL6649.and adjusted by the National Geodetic Survey in June 2019.
DL6649
DL6649.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DL6649.been affixed to the stable North American Tectonic Plate.
DL6649
DL6649.The coordinates are valid at the epoch date displayed above
DL6649.which is a decimal equivalence of Year/Month/Day.
DL6649
DL6649.Due to the release of the International GNSS Service (IGS) 2014
DL6649.realization of the International Terrestrial Reference Frame of 2014
DL6649.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DL6649.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DL6649.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DL6649.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DL6649.currently published epoch of 2010.00.
DL6649
DL6649.Additional information on MYCS2 is available at
DL6649.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DL6649
DL6649.The orthometric height was determined by GPS observations and a
DL6649.high-resolution geoid model using precise GPS observation and
DL6649.processing techniques.
DL6649
DL6649.Significant digits in the geoid height do not necessarily reflect accuracy.
DL6649.GEOID18 height accuracy estimate available here.
DL6649
DL6649.The PID for the CORS L1 Phase Center is DQ5237.

DL6649.Click photographs - Photos may exist for this station.
DL6649
DL6649.The XYZ, and position/ellipsoidal ht. are equivalent.
DL6649
DL6649.The ellipsoidal height was determined by GPS observations
DL6649.and is referenced to NAD 83.
