DI0902.Formal positional accuracy estimates are not available for this CORS
DI0902.because its coordinates were determined in part using modeled
DI0902.velocities. Approximate one-sigma accuracies for latitude, longitude,
DI0902.and ellipsoid height can be obtained from the short-term time series.
DI0902.Additional information regarding modeled velocities is available on
DI0902.the CORS Coordinates for MYCS2 web page:
DI0902.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DI0902
DI0902.The coordinates were established by GPS observations
DI0902.and adjusted by the National Geodetic Survey in June 2019.
DI0902
DI0902.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DI0902.been affixed to the stable North American Tectonic Plate.
DI0902
DI0902.The coordinates are valid at the epoch date displayed above
DI0902.which is a decimal equivalence of Year/Month/Day.
DI0902
DI0902.Due to the release of the International GNSS Service (IGS) 2014
DI0902.realization of the International Terrestrial Reference Frame of 2014
DI0902.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DI0902.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DI0902.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DI0902.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DI0902.currently published epoch of 2010.00.

DI0902.Additional information on MYCS2 is available at
DI0902.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml
DI0902
DI0902.The orthometric height was determined by differential leveling and
DI0902.adjusted by the NATIONAL GEODETIC SURVEY
DI0902.in August 2012.
DI0902
DI0902.No vertical observational check was made to the station.
DI0902
DI0902.Significant digits in the geoid height do not necessarily reflect accuracy.
DI0902.GEOID18 height accuracy estimate available here.
DI0902
DI0902.The PID for the CORS L1 Phase Center is DI0903.

DI0902.Click photographs - Photos may exist for this station.
DI0902
DI0902.The XYZ, and position/ellipsoidal ht. are equivalent.
DI0902
DI0902.The ellipsoidal height was determined by GPS observations
DI0902.and is referenced to NAD 83.
