DR3061.Formal positional accuracy estimates are not available for this CORS
DR3061.because its coordinates were determined in part using modeled
DR3061.velocities. Approximate one-sigma accuracies for latitude, longitude,
DR3061.and ellipsoid height can be obtained from the short-term time series.
DR3061.Additional information regarding modeled velocities is available on
DR3061.the CORS Coordinates for MYCS2 web page:
DR3061.https://www.ngs.noaa.gov/CORS/news/mycs2/mycs2.shtml.
DR3061
DR3061.The coordinates were established by GPS observations
DR3061.and adjusted by the National Geodetic Survey in January 2023.
DR3061
DR3061.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DR3061.been affixed to the stable North American Tectonic Plate.
DR3061
DR3061.The coordinates are valid at the epoch date displayed above
DR3061.which is a decimal equivalence of Year/Month/Day.
DR3061
DR3061.Due to the release of the International GNSS Service (IGS) 2014
DR3061.realization of the International Terrestrial Reference Frame of 2014
DR3061.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DR3061.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DR3061.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DR3061.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DR3061.currently published epoch of 2010.00.

DR3061
DR3061.The orthometric height was determined by GPS observations and a
DR3061.high-resolution geoid model using precise GPS observation and
DR3061.processing techniques.
DR3061
DR3061.Significant digits in the geoid height do not necessarily reflect accuracy.
DR3061.GEOID18 height accuracy estimate available here.

DR3061.Click photographs - Photos may exist for this station.
DR3061
DR3061.The XYZ, and position/ellipsoidal ht. are equivalent.
DR3061
DR3061.The ellipsoidal height was determined by GPS observations
DR3061.and is referenced to NAD 83.
