DK3340.The coordinates were established by GPS observations
DK3340.and adjusted by the National Geodetic Survey in June 2019.
DK3340
DK3340.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DK3340.been affixed to the stable North American Tectonic Plate.
DK3340
DK3340.The coordinates are valid at the epoch date displayed above
DK3340.which is a decimal equivalence of Year/Month/Day.
DK3340
DK3340.Due to the release of the International GNSS Service (IGS) 2014
DK3340.realization of the International Terrestrial Reference Frame of 2014
DK3340.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DK3340.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DK3340.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DK3340.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DK3340.currently published epoch of 2010.00.
DK3340
DK3340.Additional information on MYCS2 is available at
DK3340.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DK3340.** This station is in an area of known vertical motion. Due to the
DK3340.** variability of land subsidence, uplift, and crustal motion, NGS has,
DK3340.** determined the orthometric heights for marks in these suspect
DK3340.** subsidence areas should be considered valid only at the epoch date
DK3340.** associated with the orthometric height. These heights must always
DK3340.** be validated when used as control. All previously superseded
DK3340.** orthometric heights are now considered suspect and are available
DK3340.** in the superseded section. NGS does not recommend using suspect
DK3340.** or superseded heights as control.
DK3340
DK3340.The orthometric height was determined by GPS observations and a
DK3340.high-resolution geoid model using precise GPS observation and
DK3340.processing techniques.
DK3340
DK3340.Significant digits in the geoid height do not necessarily reflect accuracy.
DK3340.GEOID18 height accuracy estimate available here.
DK3340
DK3340.The PID for the CORS L1 Phase Center is DK3341.

DK3340
DK3340.The XYZ, and position/ellipsoidal ht. are equivalent.
DK3340
DK3340.The ellipsoidal height was determined by GPS observations
DK3340.and is referenced to NAD 83.
