DM2684.The coordinates were established by GPS observations
DM2684.and adjusted by the National Geodetic Survey in June 2022.
DM2684
DM2684.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DM2684.been affixed to the stable North American Tectonic Plate.
DM2684
DM2684.The coordinates are valid at the epoch date displayed above
DM2684.which is a decimal equivalence of Year/Month/Day.
DM2684
DM2684.Due to the release of the International GNSS Service (IGS) 2014
DM2684.realization of the International Terrestrial Reference Frame of 2014
DM2684.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DM2684.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DM2684.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DM2684.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DM2684.currently published epoch of 2010.00.
DM2684
DM2684.Additional information on MYCS2 is available at
DM2684.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DM2684
DM2684.The orthometric height was determined by GPS observations and a
DM2684.high-resolution geoid model using precise GPS observation and
DM2684.processing techniques.
DM2684
DM2684.Significant digits in the geoid height do not necessarily reflect accuracy.
DM2684.GEOID18 height accuracy estimate available here.
DM2684
DM2684.The PID for the CORS L1 Phase Center is DR7770.

DM2684.Click photographs - Photos may exist for this station.
DM2684
DM2684.The XYZ, and position/ellipsoidal ht. are equivalent.
DM2684
DM2684.The ellipsoidal height was determined by GPS observations
DM2684.and is referenced to NAD 83.
