DN7498.The coordinates were established by GPS observations
DN7498.and adjusted by the National Geodetic Survey in June 2019.
DN7498
DN7498.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN7498.been affixed to the stable North American Tectonic Plate.
DN7498
DN7498.The coordinates are valid at the epoch date displayed above
DN7498.which is a decimal equivalence of Year/Month/Day.
DN7498
DN7498.Due to the release of the International GNSS Service (IGS) 2014
DN7498.realization of the International Terrestrial Reference Frame of 2014
DN7498.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN7498.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN7498.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN7498.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN7498.currently published epoch of 2010.00.
DN7498
DN7498.Additional information on MYCS2 is available at
DN7498.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN7498.** This station is in an area of known vertical motion. Due to the
DN7498.** variability of land subsidence, uplift, and crustal motion, NGS has,
DN7498.** determined the orthometric heights for marks in these suspect
DN7498.** subsidence areas should be considered valid only at the epoch date
DN7498.** associated with the orthometric height. These heights must always
DN7498.** be validated when used as control. All previously superseded
DN7498.** orthometric heights are now considered suspect and are available
DN7498.** in the superseded section. NGS does not recommend using suspect
DN7498.** or superseded heights as control.
DN7498
DN7498.The orthometric height was determined by GPS observations and a
DN7498.high-resolution geoid model using precise GPS observation and
DN7498.processing techniques.
DN7498
DN7498.Significant digits in the geoid height do not necessarily reflect accuracy.
DN7498.GEOID18 height accuracy estimate available here.
DN7498
DN7498.The PID for the CORS L1 Phase Center is DR4828.

DN7498.Click photographs - Photos may exist for this station.
DN7498
DN7498.The XYZ, and position/ellipsoidal ht. are equivalent.
DN7498
DN7498.The ellipsoidal height was determined by GPS observations
DN7498.and is referenced to NAD 83.
