DO2054.The coordinates were established by GPS observations
DO2054.and adjusted by the National Geodetic Survey in August 2024.
DO2054
DO2054.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DO2054.been affixed to the stable North American Tectonic Plate.
DO2054
DO2054.The coordinates are valid at the epoch date displayed above
DO2054.which is a decimal equivalence of Year/Month/Day.
DO2054
DO2054.Due to the release of the International GNSS Service (IGS) 2014
DO2054.realization of the International Terrestrial Reference Frame of 2014
DO2054.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DO2054.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DO2054.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DO2054.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DO2054.currently published epoch of 2010.00.
DO2054
DO2054.Additional information on MYCS2 is available at
DO2054.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DO2054.** This station is in an area of known vertical motion. Due to the
DO2054.** variability of land subsidence, uplift, and crustal motion, NGS has,
DO2054.** determined the orthometric heights for marks in these suspect
DO2054.** subsidence areas should be considered valid only at the epoch date
DO2054.** associated with the orthometric height. These heights must always
DO2054.** be validated when used as control. All previously superseded
DO2054.** orthometric heights are now considered suspect and are available
DO2054.** in the superseded section. NGS does not recommend using suspect
DO2054.** or superseded heights as control.
DO2054
DO2054.The orthometric height was determined by GPS observations and a
DO2054.high-resolution geoid model using precise GPS observation and
DO2054.processing techniques.
DO2054
DO2054.Significant digits in the geoid height do not necessarily reflect accuracy.
DO2054.GEOID18 height accuracy estimate available here.
DO2054
DO2054.The PID for the CORS L1 Phase Center is DS2916.

DO2054.Click photographs - Photos may exist for this station.
DO2054
DO2054.The XYZ, and position/ellipsoidal ht. are equivalent.
DO2054
DO2054.The ellipsoidal height was determined by GPS observations
DO2054.and is referenced to NAD 83.
DO2054
DO2054. The following values were computed from the NAD 83(2011) position.
