DF4373.The coordinates were established by GPS observations
DF4373.and adjusted by the National Geodetic Survey in June 2019.
DF4373
DF4373.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF4373.been affixed to the stable North American Tectonic Plate.
DF4373
DF4373.The coordinates are valid at the epoch date displayed above
DF4373.which is a decimal equivalence of Year/Month/Day.
DF4373
DF4373.Due to the release of the International GNSS Service (IGS) 2014
DF4373.realization of the International Terrestrial Reference Frame of 2014
DF4373.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF4373.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF4373.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF4373.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF4373.currently published epoch of 2010.00.
DF4373
DF4373.Additional information on MYCS2 is available at
DF4373.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DF4373
DF4373.The orthometric height was determined by GPS observations and a
DF4373.high-resolution geoid model using precise GPS observation and
DF4373.processing techniques.
DF4373
DF4373.Significant digits in the geoid height do not necessarily reflect accuracy.
DF4373.GEOID18 height accuracy estimate available here.
DF4373
DF4373.The PID for the CORS L1 Phase Center is DJ9486.

DF4373.Click photographs - Photos may exist for this station.
DF4373
DF4373.The XYZ, and position/ellipsoidal ht. are equivalent.
DF4373
DF4373.The ellipsoidal height was determined by GPS observations
DF4373.and is referenced to NAD 83.
