DM3993.The coordinates were established by GPS observations
DM3993.and adjusted by the National Geodetic Survey in June 2019.
DM3993
DM3993.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM3993.been affixed to the stable North American Tectonic Plate.
DM3993
DM3993.The coordinates are valid at the epoch date displayed above
DM3993.which is a decimal equivalence of Year/Month/Day.
DM3993
DM3993.Due to the release of the International GNSS Service (IGS) 2014
DM3993.realization of the International Terrestrial Reference Frame of 2014
DM3993.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM3993.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM3993.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM3993.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM3993.currently published epoch of 2010.00.
DM3993
DM3993.Additional information on MYCS2 is available at
DM3993.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM3993
DM3993.The orthometric height was determined by GPS observations and a
DM3993.high-resolution geoid model using precise GPS observation and
DM3993.processing techniques.
DM3993
DM3993.Significant digits in the geoid height do not necessarily reflect accuracy.
DM3993.GEOID18 height accuracy estimate available here.
DM3993
DM3993.The PID for the CORS L1 Phase Center is DS2864.

DM3993.Click photographs - Photos may exist for this station.
DM3993
DM3993.The XYZ, and position/ellipsoidal ht. are equivalent.
DM3993
DM3993.The ellipsoidal height was determined by GPS observations
DM3993.and is referenced to NAD 83.
